It is a comfortable basement apartment (but with a lot of light), quite spacious and well furnished. My kids loved the various board games there :)
It's about 8-9 minutes walk from the metro line 5 (direct to the center) and there's a store about 6-7 minutes away (also on foot).
We had no problems, only thing I would suggest are thicker drapes in the living room - gets a bit too bright in the morning.
