The hosts (Rene and Diana) are so so nice and helpful. When we told them that our train was about to arrive earlier than possible check-in and si they let us accomodate even befor 3 PM. The self-check works perfectly and smoothly. The apartment is very well located (between two tram stations by 5 min walk and aproximately 15 min walk to U-Bahn station). It is situated in a nice old building in which we felt safe. However, the flat is quite old too. We were shocked by the gas water heater (which actually always made awful noises after we had used water). Some minor things were broken during our stay but it didn’t affect the overall stay that much. If you are looking for an apartment to just stay in for night, it will probably match you request.
