Sven communicated very well and check in was made easy with "key app". Apartment overall was unique and of great value being next to a train station. However the apartment was located next to a bar so expect an odor of cigarette smoke to permeate through the walls. Patrons from the bar are on the loud side til late hours, but in the end they weren't too bad. Just be prepared to expect some downsides, but if you are looking for a unique spot very close to public transportation then this is the place for you. To clarify, Sven was not at fault for the smell of smoke or noise. His communication was great and he was very apologetic concerning the issues.
