My husband and I stayed at Matthias’s place while in Munich for a couple of days to visit Oktoberfest. We was a wonderful host, and his English was great - which made it very easy to get around!
We didn’t feel as though we were encroaching on his space - nor he ours - as he opened his home for us.
It was a beautiful space to be, and just a quick ride on the underground to get to Munich city center and to Oktoberfest. I would recommend staying with him to any/everyone.
