I had not much experience in renting rooms in Airbnb but Mare as a host was one of the best! First of all is that all description you have below her add is most occur are I've ever seen! But room from my view was even bigger than I imagine it!
Her apartment location is in central of Munich and I wouldn't imagine better place to stay in Munich cause it is only two stations away by train/15-20 min walk to central rail station but it is in quiet area at the same time full of restaurants and cafes!
I would definitely recommend you to stay in Maren's if you are even a bit like me: friendly and open to people you meet in your life!
