Our family of six stayed with Gabi & Christina for three nights. At first, I was worried that our decision to stay in the suburbs was a mistake but it ended up being one of the best decisions of our trip. The neighbourhood is lovely with a grocery store and excellent restaurant/beer garden within a 10 minute walk. Thanks to Munich's fantastic transit system, it's only 15 minutes by train to Marienplatz.
The apartment is impeccably clean and well-appointed. It has everything you could possibly need. With four teenagers in tow, it was a dream to have three bathrooms (one attached to each bedroom) with showers in each.
Christina was a wonderful host who was eager to help with advice and recommendations. She even let us store our bags for an entire extra day while we waited for our late-night train.
This apartment is a perfect choice for large families. It would also suit three couples.
