I had a room on the 17th floor, and stayed for four nights. There was no air-conditioning in the room (which I was indeed aware of at time of booking), but when opening the window to vent, there was a constant and LOUD howling from the poorly insulated front door. So I had to vent in intervals, because the noise was driving me crazy. Luckily the temperature outside wasn`t too warm during my stay, so I was able to manage ok. The bed was not of the highest quality (you could feel the springs), but I managed to sleep ok still. Creaky floor. Very small bathroom. Now on to the positives: Lovely staff (24h reception). Fantastic location - with everything you need at your doorstep. Kitchen in the room. Great view. Room was very clean; spotless in fact. I did not experience any noise from surrounding rooms. So overall it was a good stay and I might consider staying here again, for a short stay at least - and hoping there will be no heatwave during.
