Chantal gave really great, detailed directions to get to the apartment from all over the city. She wrote down lots of recommendations for sightseeing, food, drinks etc with directions included. We had lots of privacy and the room was gorgeous. Other travelers ended up staying in the other room, which we did not mind, but could not be a great fit for everyone if they don't want a lot on interaction. The apartment is a block away from a train station and fairly easy to travel across the whole city. We took one train to go to Potsdam for the day, so simple and quick.
