Great place to stay. Comfortable, nice, lovely hosts! Very close to very good public transport.
The only thing that visitors should realize (and this has nothing to do with the lovely couple owning the place!) is that Münich is a big city. Sounds outside are accordingly. Being from a small city myself I found it pretty noisy, even in the middle of the night, especially with the windows open. But then again, all the other things made up for that :-). Sundaymornings are very nice and quiet, so you can hear the local birds sing.
