We had a fantastic time in Jonas's apartment! The apartment is huge, very clean, nicely decorated and has more than everything you need for a perfect time in Berlin. It is close to the U-Bahn station and the buses, also the bike renting place is about 15 minutes walking. There are lots of cool bars and places to eat in the neighborhood.
Communication with Jonas was easy and once we got in everything was prepared for a pleasant stay. We definitely would recommend to stay in this place!
