I was travelling with colleagues for a week long trade show in Munich in November.
Inge's house is a very comfortable place to stay with an kitchen and dining area on the Ground floor, two bedroom areas on the 2nd and 3rd floors, and a laundry and a very large bathroom in the basement.
Arriving from the airport was pretty convenient (take the train from the airport then the subway for one stop). Arriving by car, their was parking on the street for my colleague's car and the neighborhood is very calm and safe.
Transportation to the Messe takes about 20 minutes by subway and the subway station is less than a 5 minute walk from the house. You can also take the subway easily to downtown Munich.
