We stayed for 2 weeks in Mathias's apartment and had a great stay.
As he was away when we arrived, a friend met us to give us the key and show us around which made the check in very easy. The apartment itself is clean, spacious and practical for a longer stay. There were nice little thoughtful touches left for us as well.
The area is great, it feels very safe and friendly and is only a 10-30 minute bike ride from most of the major attractions/areas.
