I had a good experience staying at Gerd's apartment. Gerd was very friendly and accommodating to help me with check-in. I didn't interact with Gerd much as he was on his way back to work then Oktoberfest.
The apartment is located in a very convenient area, within walking distance from the main Munich train station and also surrounded by restaurants and bars. I only stayed at the apartment for one night so I didn't explore the area around the apartment. The listing was accurate, the room and bathroom were clean. Overall, a good value.
