I'm renting my room in the wonderful flat I share with two friends. The room is about 4x4m big, has two windows, one of them looks out to the balcony. We live right between central Hermannplatz and Hasenheide park, bordering vibrant Kreuzberg and Neukölln. My two flat mates are usually there, they're really nice and can give you some suggestions for your stay in Berlin. They will arrange to give you the keys and give you a warm welcome!
