We were having a farewell trip from our master's degree program and we got stuck in the elevator (that, by the way, was extremely warm). We had to wait more than one hour to be rescued and no one from the hotel's staff gave us any explanation/compensation. When we went to check-out next day we (without any word from the staff) asked for a compensation because of the bad moment we had (and just got half of the price discount, that, by the bay again, they have not cancelled from my credit card yet...). Really bad customer service.
