I live in a 120 square meters flat in Moabit close to the train station Turmstraße and 20 min to walk to Berlin Hauptbahnhof . My 3 roommates are very nice, open minded people with a lot of airbnb experience. They can help you with any kind of information and advices. If you want, you can smoke or bring pets. There is a supermarket 1 min walking distance. Kreuzberg, Prenzlauerberg and Neuköln are only 30 min by train.
