The location of the apartment was great, quiet area but close to the center. Nearby there was restaurants, supermarket, places to have breakfast, etc.. The apartment was exactly as described, clean and comfortable and very colorful - I loved the living room in shades of purple (the only flaw was the wifi signal, very slow and not always present, but it seems that the whole East Berlin has this problem, due to the lack of investment on the lines)
The apartment was also full of paintings, sculptures, streetart: very nice!
Overall we really enjoyed this stay!!
