Marianne's place is great for exploring Munich and Bavaria. It is quite close to public transportation and makes it very easy to get around Munich and to/from the central train station and the airport. But is a pleasant escape away from the hustle/bustle of the tourist district.
She is very knowledgeable about Bavaria and had lots of tips to make my stay enjoyable. She allowed me to check-in early and left wonderful cheescake, fruits, and chocolate, which was a very nic touch.
You can't go wrong in choosing Marianne's place as a base to explore Munich. I highly recommend her.
