Mary&Dete's place works rather more like a hotel, actually didn't meet them at all, but honestly as I was there for only 1 night, passing through Munich, that was fine. They provided enough instructions for everything within airbnb, were responsive to my questions as well. The place is quite small, which was not very clear to me from the pictures. I would have prefered that they informed me in advance that there is a construction site behind the building starting work at 7, but maybe they were unaware. Anyhow all in all the experience was ok, the place is 4 mins walk from Munich Central Station and at a good price. Should I spend a holiday/longer stay in Munich however, I would not stay there again.
