Good location. Easy access to city center, quiet neighborhood. WiFi was fast and consistent. Access to kitchen, fridge, toilet, shower. Good value.
I was meeting a friend upon arriving in Munich and rushed out of Wolfgang's place rather quickly; in addition, I am a pretty independent traveler. Because of this, Wolfgang never really had the chance to give me advice on the city, and I cannot speak on his ability to do so. However, I did see some maps and other information in the room at his place. I would guess that Wolfgang would be a valuable resource for exploring Munich.
Would definitely stay here again.
