Flat is clean. Location is very central. Very close access to S-Bahn for city. Quarter has lots of muslim foreign citicen. Street is a rather dirty side street. I would not recommend it for my daughter but all of this was not at all a problem to us. Shopping of all goods and food is also very close. Door to pavement is direct door to living room with direct view to bed. Bed room for two people is behind.
In short:
clean flat, very central and close to food shop. best for two people, who do not care of a bit dirt in the street and walk along with foreigners.
