Our stay was ok. Unfortunately we got a room in the first floor and the window was facing a big street. I suppose upper rooms might be better. There was a lot of construction work going on in the Airbnb, e.g. in the kitchen. When they are done, it might be more cosy and clean. Also, the staff was really friendly!
All in all we were out all day - and for sleeping this apartment was totally fine (just be aware that you'll probably hear your neighbors...).
