Nice place in a fairly 'gritty' suburb of the old east Berlin. The local U-Bahn is closed so it's a hike to the nearest one.
No TV in the apartment but wifi is good.
The apartment would really suit larger groups and offers good value for 6 people. One of the showers was flooding the bathroom and reported but not fixed during our stay.
The host was 45 minutes late meeting us at the apartment despite clear instructions. We missed some of the concert we were attending because of this.
All in all I would say there are better places but if you need a place for 6 in a budget area of Berlin then this is ok.
