The flat is very well located and Barbara is a nice and helpful host. She responded all our prior doubts very quickly and she was waiting for us at our arrival and provided useful info and tips about Munich. The appartment is perfect (except the TV that was not working properly) and Barbara offers milk, homemade jams and other tasty food.
Having said that, the only "con" in our opinion is that sometimes - during working days- Barbara is not renting the whole flat (as the main page of their advertisement said), because she may also need it. In our humble opinion, at least in our case - a family with two children on holidays - the work schedule is hardly compatible with holiday schedule. You may feel that annoys or you may feel certain lack of privacy or being awaked very early in the morning. It would be coherent then to pay different fees, depending on sharing or not sharing the flat with the owner.

To be honest, Barbara told us - just arrived at the flat- that she had a cancellation on her flight and we, politely, accepted to share the flat misunderstanding that it was only one night. How are we going to say no to the owner of the flat being our second experience with an airbnb flat?

Finally, what it came to us as a surprise is that the sharing was the whole three-day stay.
