Babett was very kind and welcoming, explained how everything works in her apartment and gave good suggestions for places to visit and restaurants/shops close by. She offered tea and coffee; there is a good espresso machine :)
The apartment is a 25 min walk from the center (or 5 min from the u-bahn) in a quiet neighbourhood. The room is bigger than you would think from the pictures, you can use the kitchen and take a nice hot shower after a long day.
I would definitely stay at her place again if I was in München.
