Let me start by saying that the host, Reinhard, is such a lovely guy and he helped us with everything we needed.
The apartment is brand new, clean and modern, really comfortable for 2 people and in a very quiet zone of Berlin.
Parking may be an issue if you arrive late (which we did, but that was our own misfortune), but the city center is really easy to reach (20 minutes from Sundgaer straße) and generally you won't need a car for Berlin.
