My partner and I had a good stay at Matthias’ place. The check in was with Friedrich and it went very smoothly. The location is honestly excellent (not sure if you could do better!). The downside was the ammenities of the studio are very limited, the bed was uncomfortable (thin mattress on the floor in the mezzanine) and the place didn’t feel like it had been thoroughly cleaned (it wasn’t bad, but we both suffer from allergies and the carpets probably needed a deep clean to get rid of dust etc.). If you are out a lot exploring the city I am sure it is fine, and the location is definitely the studio’s biggest asset, just depends on what you value most in an airbnb :)
