This is actually an inn, not a private room in a family's flat as expected! Even if Claudia was nice, this is not what we had reserved for. Instead of sharing adresses, experiences, memories... And discovering the city through the hosts, we felt we'd come into a rigid organization : "do not speak when you're in the stairs", "be careful when you clap the door", "hotel tax now please", "put your shoes off and place them here, only here where the room's n'aime is written"... We were even more disappointed as we were just leaving a great Airbnb guest in Berlin too, who was very communicative and with who we shared a lot.
However, the room was very clean, looked like the photos had showed it and was very very central, in the district we loved the more in Berlin. There is a big great park not far from the flat and the metro just at the corner down the street. I recommend this to people who are just looking for a place to sleep, no for personal experiences or sharings with people from the city.
