We were very excited to come to this hotel -great design, good reviews, excellent location. Unfortunately our high expectations came down to a huge disappointment. 
The first room we were given was on the second floor, facing a nearby building and the air conditioning machines. A horrible room for over 500€ a night. We have immediately asked to change room and after a while were offered another room on the 8th floor. While the location was pretty much the same (looking to the wall of the neighbor building - nothing in the description of the room indicated this - really bad from Hotels.com!!!) but the real problem came with the humidity and mold. The smell was evident. We then started looking and it was all over the place, from the lobby to the corridors to the rooms. It’s an absolute shame - this hotel should be closed and they should repair this problem. Hotels.com should not make reservations in this place as it is completely off the standards one should expect.
