I stayed at Karin's place for more than two months. The house is very well positioned: 2 minutes walking to both U-bahn and S-bahn (Harras): nothing better you can ask for in Munich! The neighborhood is really nice and you have everything you need at walking distance: supermarkets, bars, swimming pool, etc.
The room is very cozy and nice. I stayed there with Karin's husband, son and Cat: they made sure my stay at the place was as pleasant as it could get. Whether you like cats or not, Elvis is a very discrete presence and won't bother even in the latter case, but if you like cats he's a really enjoyable company. The room is large enough, it gets warm quickly (not bad in Muich's winter) and spaces are not an issue as the house and the kitchen are big.
Shall I be back in Munich, I definitely would like to stay at Karin's again!
