Ben's place is awesome. The flat is really well designed and laid out. The pictures are accurate if not a little less than what is really going on there. It was very close to a number of restaurants (Hoa Lan is a great spot), groceries, cafes, and bakeries. We thoroughly enjoyed our stay and would highly recommend it to others.
It's extremely close to the S Bahn so connecting to the center and public transportation hubs was very easy. The park that runs along the river was a nice natural amenity only minutes away that exhibits how some Berliners take advantage of their diverse city offering. Without a doubt, we would stay again.
