The first room I was given was on the third floor. When I went to sleep that night the sound of a nightclub next door could be heard clearly through the wall, and the music actually shook the bed/walls. I figured it would end soon, as it was already nearly midnight. It did not end until 5am and so I did not sleep. When I told the front desk, they admitted it happens on the entire third floor but said some people don't care. Well, they should ask whether you are a light sleeper or simply don't want to hear music all night before booking you on that floor. I had meetings the next day and it was a struggle without sleep.
The hotel did move me to the sixth floor the second night and I slept well -- no noise, and a bigger room. That's also something to note. The single room is incredibly tiny, which wouldn't be a problem if it were set up better and had the amenities specified. For instance, no safe (the hotel did provide a moveable one when I inquired). The bed is crammed between two walls, so if you're tall your feet will touch one. And the mini bar does not include a fridge. There is also no shower separator so you will have a wet floor when you take a shower. It's not terrible, but considering how easy it would be to put up a curtain or half-glass wall it's bothersome. Also, absolutely no counter space in bathrooms -- not even a place to put hand soap. The twin room is much better -- it has a safe, fridge, and more space to move.
