I loved this apartment!
It's big, comfortable and designed beautifully. Price is very very fair.
Really great location - next to Mauerpark which has a great market on Sundays, and in Prenzlauer Berg which has lots of cafes, restaurants and bars. A few minutes walk to public transportation.
Dirk was very warm and welcoming and is a wonderful person to sit down and have a conversation with. He was in the apartment for only part of my stay but helped me and made me feel at home.
