Ralf is a great host. We arrived late, but Ralf was waiting for us at the door steps. He greeted us in person, and showed us the room in detail. He responded to messages quickly, and was very helpful when we had to make some changes with the reservation.
The room is exactly as showed in the pictures. It is very clean and stylish. The location is great, close to tram stops with a lot of good choice, but is quiet at night. Because half of the room is below the ground, the room is not that bright. But since we spent most of the time outside in the city, it is really not a big problem. Ralf’s place is very recommendable.
