Very clean, very comfortable, and very close to an S-bahn stop, making it easily reachable from the main station. Klaus was friendly and provided plenty of information and a map of the city. We enjoyed the walk from the apartment to the centre as there is an area with markets on the weekend. Klaus went away over the weekend leaving us on our own in the apartment, which gave us plenty of space, although it was nice to talk to him when he got back. Thank you Klaus, we hope to return to Berlin soon!
