This was the 4th time I stayed at this hotel over the course of 18 months. Personally I think standards have slipped. General cleanliness of the hotel has slipped. The first time I stayed here I gave it 5 stars for cleanliness. 18 months later the standard has dropped. A trash bin at the entrance to the hotel was full and stayed this way for 3 nights, I left today and it still was not emptied. My room was clean enough to not complain but could have been better. The overhead shower head was full of limescale and the jets of water suffered as a result. The bin in my bathroom was full with sanitary towels and had not been emptied prior to my arrival.

Breakfast choice has also slipped over the time, jams rarely replaced and a poor selection of available food to be blunt.

Overall nice enough to stay but the hotel has proved it can do better.

En mi toda mi vida de viajero.. tengo 62 años he encontrado tantas cosas malas en un solo lugar
1 - Llegamos media hora antes del la hora del check-in no querían cobrar 59 euros si queríamos entrar. Pues nos sentamos a esperar que fueran las 1
2- Dice que tiene aire acondicionado y no tiene.
3- cierra en portón d entrada a las 9 pm y hay que llamar portón teléfono para que lo dejen entrar.. el problema que el plan que compramos de teléfono es solo para internet.. así que tuve que subirme como un ladrón en el portón para poder llegar a la recepción para que nos abrieran.
4- La puerta del baño no cierra
5- No dejan jabón. Si se ocupa debe bajar a la recepción.
6- La secadora de pelo no sirve
7- El personal nada amable en ves de tratar de solucionar fue retador
En fin no lo recomiendo ni de regalado

hmmm…

they have a locking gate for cars to pass that requires a phone call to have unlocked after day time hours , and can take long time for someone to pick up. Room key needs re programming nearly every second time used - needs an overhaul

Bon hôtel

Nous avons fait une escale d'une nuit dans cet hôtel sur notre trajet de vacances. La situation par rapport à l'autoroute est bonne. Il y a un parking assez vaste. L'accueil est bon avec un check in rapide. La chambre est propre, les lit sont bien confortables. La salle de bain est ok avec une douche a l'italienne. Petit dejeuner-buffet de bonne qualité et bien achalandé.
Nous n'avons pas vraiment testé les alentours de l'hôtel vu quenous ne restions que la nuit.
Nous sommes repartis bien reposés le lendemain.

Hotel well positioned for purpose, visiting Marcoussis for a competition. Carrefour and garage nearby and lovely Italian restaurant within a few minutes walk.
Although a good deal obtained for room rate we were told on arrival that breakfast was included, and then on check out told it wasn't. Breakfast is Euro17.90 per person per day, and mediocre at best, certainly not worth this amount.
Hotel also said they could not accommodate our request for a twin or family room yet we discovered others that had been given a family room but only needed a double.
Advice - certainly worth staying but look at other options for eating.

Pricey for an overly warm room

In general, the Mercure is fine for a short business stay but tends to be on the high price side since there are not many options in Les Ulis. I stay there several times per year. The restaurant is nice and the people are friendly. The main issue with the Les Ulis Mercure (common to IBIS, Mercure and Novatels I have stayed in) is with the temperature of the room. Although there is a thermostat, there is, in principle, no air conditioning,(if so, I have never seen it work in 5 years of going there). You can open the window but the heavy curtains block the air flow. If you open the curtains, you suffer from bright lights on the outside of the building and significant noise. (It is close to the expressway and airport.) If you need a cool room to sleep, you may have a problem at the Mercure.

Hotel is a bit tired and not really in nice surroundings, but the staff were really friendly, excellent value and was ideally located for a stop travelling back from the South of France.

convenient location

Lovely room and very friendly staff. The hotel restaurant was not open but there was a good selection of restaurants nearby which we were given directions for from reception. Our only complaint was the breakfast. at 17 euros each it was poor value for money. There only appeared to be two members of staff on and whilst they were doing their very best to be helpful, they were unable to keep up with maintaining the selection on offer and meeting the needs of what appeared to be a large party of Japanese tourists who were also staying at the hotel!

Mercure Paris Sud

Comfortable hotel, pleasantly surprised to find the family room consisted of 2 rooms rather than squeezing extra beds into 1 room. Very helpful staff who spoke English. Pool was a nice feature if a little cold as it wasn't heated. Breakfast expensive at 16 Euros but lots to have and the kids ate for free. Would recommend this hotel and stay there again.

Das ganze Hotel erinnert an eine Hochhaussiedlung.
Der Empfang war eher bürokratisch als herzlich.
Wir hatten um ein ruhiges Zimmer gebeten, bekamen aber eines, das zur Schnellstraße ausgerichtet war, Zimmer 308.
Der Lärm war schon sehr deutlich zu hören.
Die Klimaanlage im Kinderzimmer war defekt und im Elternschlafzimmer ist sie sowas von laut, dass wir das Gefühl haben , es fährt ständig ein Zug an uns vorbei.
Obwohl es zur Zeit gerade mal 20Grad warm ist, war es im Zimmer schon unangenehm heiß , da die Klimaanlage so gut wie gar nicht funktionierte.
Wir müssen jeden Abend mit geöffneten Fenstern schlafen und bei der Lautstärke 😡….. Ich weiß es nicht, wie es da im Sommer mit dem Schlafen aussieht.
Zum Glück war das Hotel ziemlich leer, sodass es so gut wie keinen Lärm von den Nachbarszimmer
zu hören war.
Die Matratze im Elternzimmer war schon ziemlich durch und könnte erneuert werden.
Angenehm waren dagegen die Kopfkissen.
Das Frühstück war im Ganzen in Ordnung
Insgesamt kann ich mir einen längeren Aufenthalt in dem Hotel leider nicht empfehlen.
