We booked a non smoking room, I think just the first floor is non-smoking.
As soon as you get to the elevators thats all you can smell is cigarette smoke, the hallways on the upper floors very strong smelling of cigarettes, the room wasnt as bad as the hallway, the room did smell strongly of cigarettes though. (smoking room).
I think if your a smoker its a good place to stay, if not make sure you book the non smoking room cause, chancing it in a smokers room isnt gonna be worth it.
