The place was as described. Sebastian was really nice and met us at the flat and then took us for a little tour around the neighborhood. There's a supermarket just around the corner, cafes, restaurants, bars, two metro stations within walking distance. It's a really nice and quiet residential area, but you won't be bored. It's quick getting to most of the important spots in Berlin. We really didn't miss having a living room since we only came home to sleep. There's also a nice sunny balcony to have breakfast or coffee in the morning. The beds were really comfortable and the rooms quite ample. I'd definitely go back to Sebastian's flat if I ever return to Berlin!
