I got the worst possible room 101 at Level -2, which was extremely loud due to a very noisy AC or whatever mashine it was outside next to the only window, which could be opened. The room had a terrible smell. There were small black bugs in the bed, on the walls, in the bathroom. I have asked immediately after checking in to have the room changed, but I was told that I haven’t paid for a better room (if you consider a price of CHF 248 what I was paying per night as a low price, where colleagues of mine who stayed at the same hotel paid less but had nice rooms on 8th floor with a view, fresh air, etc.) few photos of the bugs on the bedsheets and on the walls are attached.
