The rooms are all non-smoking but most, if not all smell like cigaret. I changed rooms 3 times and the last one didn't smell like cigaret because it smelled like the bathroom pipes.
Thinking of charging your phone next to the bed? Not possible, it only has plugs in a corner of the room.
Free Wifi? Yes, but only in the 3 rooms close to the router in the corner of the floor.
Sleep well? The building has more echo than a stone cave. I could clearly hear my 7am neighbor conversation on the phone, and the kids yelling in the hallway.
