We received a warm welcomed from the mother who showed us around the place and gave us all the info we needed.
The apartment is located in a most wonderful neighborhood. Very sociable with lots of pubs and restaurants.
Tram at 2 minutes walk, with frequent connections. So the whole of Berlin is within reach.
The apartment itself is comfortable enough, with everything you need. We didn't spend a lot of time there, because we were out and about from 8am until 10pm. But we thought ourselves very lucky to have found this place.
