Daniela and Fritz's place is a lovely underground apartment in the hippie-ish suburb of the Allach. From there, you can enjoy a nice walk on the forest, a good sightseeing by the lake and some good, quiet places to chill in outer München.
The place is relatively distant to supermarkets or to S-Bahn stations, so you'll either have to walk a little or get a bike (which the hosts usually gently lend to you).
It's a very cool place and received us very well in our arrival in Germany.
Danke schön!
