Jan is a very friendly guy that will make your trip in Munich easier by provinding you information (apps, tips, recommendations etc). Also, he is an easy to talk to guy, you can chat with him about everything. I met him and we chat for a while and I definitely felt like we were old friends :D
The house was super clean and the room was pretty big. It's located in a nice and quite neighborhood, about 10-15min from the center of Munich by metro. There are some restaurants and groceries stores nearby. Olympiapark is pretty close too.
