So, just for you to know what to expect so to be everything clear. It was not so clear for us. You will stay in the same apartment (4th floor, no elevator) with Stefan and Linh. They have a part of the apartment and you will have 1 big room. The room is perfect. Also, you will share the bathroom and kitchen with the Stefan and Linh and might get tricky while you wait for the bathroom to be free in mornings and evenings. Bathroom is clean and big. Kitchen not so much and there is little room in the fridge for guests. Apartment is in a nice town close to Munich and is right near S7 Sbahn station. You can see the station from your room window. But we were able to sleep very well at night and train noise did not bothered us. It is convenient to be so close to train station and on a direct line to center Munich. Parking is wherever you find an empty place on the street.
So if this is what you are looking for and close to Munich and price is important, then sharing an apartment is not that bad.
