I'm sharing a really nice apartment with two other persons (25 and 28) in Kreuzberg. My room is 21 square meters big and has everything need during your stay. The apartment is near a metro stop and many bars, parks and grocery stores.
Please don't smoke in my room and also don't bring a pet. I love my couch and I want it to stay clean. Therefore please use the little couch table or eat in the kitchen. We have a cleaning schedule that you would have to live by. So once a week you'd have to help clean a bit. That's it...
