We loved staying in Ben and Olga's lovely penthouse apartment. Olga met us when we arrived and made us feel very welcome, even leaving us food and other small things to make our stay pleasant. The large terrace is particularly lovely - sunny with nice views and comfortable furniture. We ate every meal outside and hung out late into the evening with our 2 kids on the comfy terrace sofa, talking and reading. It is a comfortable home in a good location -- a quiet oasis from the noise and bustle of Berlin. Highly recommended!
