Great location, close to a lot of the subway lines but far enough from all the hustle and bustle. I also appreciate how secured the building is - from secured elevator access to 24 hours security guards.
I actually stayed in 2 different floors/rooms here and do agree that the walls are thin, so you'll hear your next door and upstairs neighbors. Best accommodation is probably the corner suites since the rooms do not have any any shared walls.
10/10 would stay here again!
