we stayed for two night in the room. The contact was nice and everytin went smooth on the day of our arrival.

The room is quite large and the high bed is very comfortable, nothing to complain here :)
Only the bathroom could use some renovations (It is for Berlin standards still fine though).
The flat itself is very close to "Kottbusser Tor" from where you can get everywhere, shops and restaurants are all close by.
