I really enjoyed my stay at Karin & Bernd's flat! It's in a quiet area, surrounded by trees and in easy walking distance of the Grunewald forest, but it's still easy to get into the city centre if you want. The flat itself is also very quiet, thanks to the double glazing which also keeps it nice and warm. It's also very well equipped, plus Karin & Bernd are great hosts, so I definitely recommend a stay here and hope to come back myself!
