Dirk is a kind host, who is very helpful and answers all of your questions about e.g. transport from the airport or the highlights of Berlin.
The private bathroom has a nice shower and bath, and is very clean. Furthermore, the bed is comfortable, which enables you to wake up well-rested for a day of sight-seeing or to enjoy the neighbourhood. Prenzlauer Berg is lively, with many restaurants, Berlin's oldest beergarten and the U-bahn nearby.
Major plus was that Dirk welcomed us on Sunday morning at 9:30 AM when we arrived from the airport .
