At the first contact with Rainer via AirBnb, he was very kind and easy going, always informing us about every detail of the booking.
The apartment is simply perfect. Very clean and well lit, it has everything that you need. Location, location, location. 5 min by walking from Westbanhof station.
Another plus is the Rainer's concern to little details, providing us tips about the apartment and the city (restaurants, sightseeing, transport).
I strongly recommend Rainer's place.
