I travel to Europe multiple times a year. I stayed at two other hotels in Portugal on this particular trip. Same procedure everywhere. Pictures of the passports, confirm payment for the room and incidentals, sign.
My flight was early in the morning. My companion's was later in the day.
She stopped at the desk as a courtesy to let them know that they could clean the room. Their response was to hold her and make her pay for the room and incidentals even though it was already taken care of. They humiliated her for almost 5 hours. Of course she was embarrassed at her treatment, and panicked that she was going to miss her flight. Her credit card was frozen because of the random international charge. She was reduced to years.
She managed to secure all but 250 Euro through friends back home until finally they used my credit card for the balance.
I have never even heard of a hotel with such blatant disregard for hospitality or basic human kindness. They took distinct pleasure In hurting a person when they had the ability to satisfy themselves the whole time. They just chose not to.
During our stay, we couldn't figure out why something was just off. The staff was either smug and callous or operating out of fear. It's clear that this is a foundational culture issue that will pollute your experience.
I would highly recommend you choose somewhere else to stay.
