I stayed in Miriam's flat for six nights. Her apartment is lovely and warmly decorated, and clean. It is as described, except that there is no TV set.
Miriam was not in München to welcome me and, upon my arrival, I could not enter the building immediately, because we both forgot to communicate about the key lock code. However, Miriam was really reactive with this and I did not have to wait at all!
The location is perfect, only 5-10 minutes away from the subway, and from this stop, you get to the city center in less than 15 minutes. You also have a Rewe supermarket nearby.
Miriam was very concerned about me enjoying my stay in München in general and at her place more specifically. She enquired several times during my stay through Whatsapp if everything was okay :-) and gave me some suggestions regarding nice areas in the city, sites of interest and restaurants.
I definitely recommend staying at her apartment if you plan to go to München!
