I rent my room the north of Neukölln in Berlin, close to Kreuzberg.
The room has 18 square meters, and a balcony with about 2-3 sqaure meters. The room is fully furnished, and has everything you need.
Of course you can also use the rest of our flat, kitchen equipent and so on...
If you have any questions, just let me know.
I´ll be out of Berlin from Tuesday morning for about one week.
