Stephan and Marcel are wonderful hosts who gave us a map marked with restaurants and grocery stores. A special treat was the swimming center nearby - there are actually 2 options, a fully outdoor complex complete with 10m high platform diving and a mostly indoor space that does have a fun outdoor portion. Tickets are sold separately and there is no combination option. If you like to have full locker room services go for the indoor. The outdoor complex has places to rinse off out in the open and of course toilets but no showers. Going there is more akin to a day at the beach - 4 giant pools with water slide!
I was originally concerned about being out from the center of Munich but it turned out to be a real advantage as we found ourselves among the local people rather than throngs of tourists (at least in July when we were there) and the quality of food (as well as price) was better. The beer garden Stephan recommended was leisurely and relaxing.
