Matthias is a very tentative host. He answers any questions and is very helpful. The apartment is wonderful. It is spacious, exceptionally clean and complete with surplus glasses, plates and even toilet role. The bed is very comfortable and the balcony is great. It has a good view of the courtyard which is also pretty.
Location is good! There are nearby places to eat as well as bars and a supermarket a few doors down.
The street is relatively lively but the apartment is exceptionally quiet. You will not hear a peep and will enjoy a good nights sleep.
I would stay there again for sure if Matthias would have me.
His son Fritz met me with the keys and he was very polite and helpful. The tram/bus/subway stops are all very near within a 3 minute walk.
