Great place in a cool location in the middle of the many of bars, restaurants, cafes and flea markets of Friedrichnhein, with a bus stop just across the street, as well as S- and U-Bahn stations within 10 mins walk. Everything we wanted to see was within a 30 min trip door to door.
Minimal storage for hanging clothes or unpacking, so for 6 people it's a little difficult for more than one or two nights. Note that there is only one mirror, in the one bathroom, so a large group getting ready in the mornings and evenings takes a while! The kitchen is well kitted out for 6 people to have drinks and breakfast etc.
Very clean and very good communication.
