My stay at Jan's during Oktoberfest was great. I arrived late on a Saturday night but he was still up and showed me around the apartment, making sure I was comfortable and knew how to find and use everything in the kitchen and toilet.
He also recommended the MVV app for Munich travelers, which I found invaluable and used every day to plan my trips and buy public transport tickets.
The room is comfortable and more than enough space for one person. There are places in the neighborhood to buy food or get a coffee, and the bus and subway stops are also nearby.
I had a great experience in Munich staying at this apartment, and Jan even gave me a souvenir when I left!
