My boyfriend and I are spending a couple of months in Berlin, and rented Duc Son's place for my parents while they were visiting us here.
The place was very spacious for two people, with a generously-sized bathroom, and extra bedrooms. The furnishing is spare - it feels like a rental unit, with minimal decoration - but the location was perfect for us, and my parents especially appreciated that the windows opened onto the inner courtyard, so the apartment was quiet while still being in a lively neighborhood with plenty of restaurants and shops in easy walking distance.
