Steve's apartment is everything you can wish for your stay in Berlin. It is quite central, easily accessible from three different U- or S-Bahn stations and located at a 40min walking distance from Zoologischer Garten or Potsdamer Platz, if you enjoy walking like I do.
The interior is beautifully designed, very warm and homey, and confortable. We felt at ease immediately.
Steve is very welcoming and easy to talk to. I highly recommend his place.
