The apt is actually nicer than it looks in the photos. Very clean, well furnished and quiet. The location is great: very close to the city center and, with the U6 just a few steps away, you can easily reach everywhere. Overall good value for money :) Karsten's directions to reach the apartment were very precise and helpful. We felt very welcome on our arrival and, despite the late hour, he spent quite a few time with us to suggest places to visit, restaurants and so forth.
