I highly recommend Dassia's place. I stayed here for one month, and both Dassia and her partner were great hosts. They were very hospitable and friendly, giving me advice and always happy to include me in conversation. I felt very welcome. Considering that they are a young family, the apartment was quiet enough for me. The location is perfect as it is very central - great access to local amenities and public transport as you are less than five minutes from the Ostbahnhof by foot. I'd definitely stay here again if I'm in Munich.
