For us what stood out were the staff, the quality of our room and food.

This hotel is perfectly located if you want quiet but dont mind a 5 min walk to the beach or the town. The taxi services are great for further afield areas. Would we come back. Definitely.

Handy for Argostoli & exploring Southern Kefalonia

A really nice modern hotel, with a nice pool area. Really good restaurant (fantastic gyros!). Front desk really helpful sorting taxis and car hire (really efficient service for that!). Rooms a good size and comfortable. Only down side was that the balcony rarely had any sun on it, which made the room a bit dark as just patio doors for natural light (we had a Design King on east wing at front). Also there is a new hotel being built over the road so some noise and nearest beach therefore unusable. Should be finished in 2026. Also quite windy when we were there in September but pool area fairly sheltered (S side)

The hotel grounds were beautiful and the architecture was impeccable. It captured the energy and essence of a true Greek island. The swim up suite was perfect for our couple getaway.
There were 3 areas of improvement that could have made this an 5 star review.
1- the wasp nests that were located on the ceiling of the outdoor seating area for breakfast. (See picture and note)
2- a sewer smell that would come through the room from the drain of the shower.
3- A/C remotes were locked to slowest fan speed making it either really warm or cold in the room.

Great stay!

This hotel was one of our favorite hotels we have stayed at in some time. Very friendly staff and the food here is amazing. They have live music some nights which was also so fun. Very comfortable spacious room with so much closet space. I would definitely come back here.

Thalassa Boutique was the perfect resort for our stay in Kafalonia. The only amenity that would have been helpful would have been an ATM machine. A small gum would have been nice too. Overall hour 9 night, 10 day was superb.

On check in was told swim up room I booked was not available, would not refund so we could book a swim up at another hotel (which is what we requested) so had no choice but to accept the standard room offered with no reimbursement for the difference in price. Terrible service do not book with Expedia or stay at this hotel!

The staff are really lovely and helpful. The hotel was clean and the pool area and restaurant were fantastic. Short walk from a few really beautiful beaches and walking distance to many restaurants in Lassi. The hotel restaurant served excellent food and drinks and the view of the sea from the hotel is amazing. While the furniture in the room was dated, it had everything I needed and was large. I especially enjoyed having a sea view and my own seating area outside. I really enjoyed my stay and hope to return some day.

We showed up to the hotel after 24 hours of travel, we had booked a swim up suite for 4 nights. We arrived and they told us we could not have the room we booked 5 weeks in advance, they gave us an old basement room for our first night. I asked them to return the difference of the room prices to us, and they bluntly said they would not return any money to us.
I asked again the next day, they said they would give us a free dinner at their hotel. I said no, I want the value of the room returned, and they said no. Our service was terrible after this the entire time. The servers at the pool bar were very pleasant, the only kindness we received.

What an amazing hotel. Lovely rooms that are meticulously cleaned each day and given the turn-down service at night. Fantastic food, not only the sumptuous breakfast buffet that's included, but also the lunches and dinners a la carte - all served by friendly, smiling staff. Oh and then a cocktail bar with a glorious view to start or end the night. Cannot fault it.

We stayed here for 5 nights in July and it was amazing! The hotel is beautiful, the images online do not do it justice. It is quiet, and even in peak season was not super busy. The staff are lovely, and food and drinks are amazing. We were upgraded which was a suprise and the swim up rooms were incredible. We will definitely be staying here again!

Thank you!

Great hotel with lovely design features. Our initial rooms aircon unit had a fixed temperature so it was like an oven at night. In such hot conditions this wasn’t great - especially when they told us the technician had fixed it and it couldn’t be amended. Only to find out that other guests could control their desired temperature. After 2 nights we had to say something and they changed our room.
Everyone comments on the lack of umbrellas by the pool and it’s true - it’s ridiculous and I dont understand why they don’t do anything to resolve it. The only other challenge he is there’s nowhere for guests to shower if you have a late flight.
Other than that we had a great stay. Great staff and beautiful views etc

I liked the hotel and the layout, the pool area, is very good looking, the average age of the people staying there is probably late 50's to mid 60's so you can be pretty much be assured that you won't get a football or a frisbee flying across the pool area, there is a beach near the hotel where you can watch the sunset called Makris beach.
The WiFi in the room was very temperamental, the actual rooms are very very good looking apart from the front door to each room, which is strange, if they were to be changed then that would be a great bonus.
George at the bar by the pool is brilliant along with the staff there and the staff at the bar in the front by reception, I can't fault any of the staff and there are too many to mention, but they were all great!

Lovely hotel and very friendly staff. Only issue which put a dampner on things at the start was a sea view room ( for which we prepaid ) was not available on arrival so wd had to settle for a different room for first night. This was happening a lot with new arrivals and some rooms are lovely but others very dated so not all as per lively pictures.

Probably the most expensive hotel in the area but a little overpriced although staff were really nice

Pool area bar really nice but a 10 min walk into Lassi and everything at least half the price

Overbooked - room changed!

Check in was quite bad as the room I booked was not available so they gave us a room on first night and then had to switch the second night to another room which was inconvenient as was unable to unpack and had to live out of a case for over a day. Also couldn't check in as room wasn't available at 1500. This seemed very common, as on numerous days we watched people moving rooms so they seem to overbook and then make customers move rooms the next day.... Not a great service!

Once all above resolved, hotel was nice, comfortable and friendly staff.

We really enjoyed our stay there! We had a room with sea view just renovated. The staff is very friendly, kind and polite. The breakfast buffet is very rich and tasty. We also tried the food in the pool bar and it was delicious. The hotel is very close to both the airport and the capital of the island. It is also located close to the best beaches of the area of Argosyoli, so you can’t go wrong with this choice.

I stayed at this hotel for three nights at the end of September and was blown away by the beautiful surroundings. The pool is a tranquil escape where you can take a dip and soak up the sun with the smell of olive trees and lavender in the air. The staff were so friendly and helpful. Me and my boyfriend have said we would definitely go back and recommend to family and friends. The al la carte menu had some great dishes; the happy hour was great and the view from our balcony was beautiful. The hotel is a short walk from bars and restaurants in Lassi and evener shorter walk to a beach. I had a wonderful stay.

Great hotel, lovely stay!

Great hotel in a perfect location. Close to airport, but no airport noise. Could walk into Lassi for lots of dinner options in 5 minutes or into Argostoli for even more restaurants, bars and sites. Hotel was very nice, 2 pools, good breakfast, decent prices on drinks at the pool bar and good lunch menu at the pool. Room was clean and comfortable, with recently updated decor and a nice balcony overlooking pool and out to the ocean. Could walk to 1 beach in 2 minutes, or a much larger, nicer beach in 10-15. Highly recommend!

The hotel was beautiful, although I actually stayed in what was once Silo apartments at the back of the hotel, which was not as good as the main part of the hotel.My room was very nice, but it could have done with a few extra comforts. There was absolutely nothing in the room with any information on it, like how to call reception or even how to dial out. No information on any local places of interest. A simple thing, no do not disturb sign for the door, so consequently housekeeping were forever opening the door to come in when I wasn’t ready.
Housekeeping came in every day but was very hit and miss. Sometimes the towels would be changed, sometimes not. Sometimes the bins would be emptied, sometimes not. The sink was not cleaned for several days in a row. The balcony was messy and the table was never cleaned.
It was €3 for a pool towel which I was told I could exchange every three days. What they did not say was that I would have to pay €3 every time I did that.
The pool bar was very nice, and what little food I had there was good, however, you could not buy a cocktail there.
I wanted to buy a sandwich and a drink there one day to take to my room, I was told it would cost me €5 extra for room service, even if I took it there myself and brought the plate back afterwards.
So although I enjoyed my stay, there is room for improvement, considering the cost of the accommodation.

This boutique hotel is beautifully decorated and has a calm manner. The manager Angela and all her employees, especially Muhammed, were very welcoming and always happy to help.
We stayed in a recently decorated standard room, with an amazing shower.
A great proximity to both beaches and restaurants with a 20 min walk to the capital Argostoli.
I would definitely recommend this hotel and will be visiting again.
