The flat was perfectly clean (the room, bathroom, and kitchen) and furnished with all equipment. Even if the room has no window, it was quite cool and I slept very well. The neigbourhood is really nice, and well connected with the city center.
The quality of your stay will depend much on the other roommates: the three rooms are separated just by very slight doors, and you can hear even a whisper in the other rooms. So I would recommend to bring hear plugs.
