The apartment is very nice in a very good position, very close to the bus stop and the S-bahn. Due to our flight schedule we needed to check in late, so Buse make sure to leave the keys in the mailbox so we were able to enter the apartment. We had just a missing towel (2 instead of 3) and the host told us just few hours before checking in.
Buse let us check out after the regulat check-out time and this has been much appreciated.
