As aforementioned, this is a perfect place to stay if you are 1. looking for an ultimate accommodation in a residential neighborhood with local experience that only AirBnB can provide, 2. driving and in need of a secure parking space (albeit not enclosed), 3. yearning for a meaningful interaction with the owner.
We are 2 couples coming with a car, and received the most welcoming introduction to the house by Robert, Mark's father, who waved at us as we drove up the street. The fridge is fully stocked and he carefully explains how things work around the house, as well as give us parking tips and directions to the nearest grocery store (Edeka, only a few blocks away), and S-bahn station (Untermensing on the S2 line, also very close, and only a few stops away from innenstadt (Hauptbahnhof, Stachus, Marienplatz, etc). We drove to BMW Welt, which took less than 15 minutes.
Mark's unit is on the upper floor (not suitable for people with physical limitations), with beautiful furniture and complete amenities. Plenty of windows to let air and natural light in during our visit with unseasonably warm late September weather. There are 3 balconies to choose from for you to relax. Very quiet (with occasional trains whizzing by), and therefore not suitable if you plan to have loud activities. Ample indoor space for up to 6 adults, but the third "bedroom" is an open mezzanine (so no privacy), and both bathrooms are en-suite. Overall, one of the best AirBnB experience we've ever had.
