Very nice apartment right across the street from the Munich Central Station. (Munich HBF) So it is convenient to walk to many of Munich's attractions: Marienplatz, English garden, Oktoberfest, etc. It is on the 7th floor so it is very quiet with the windows closed. (And an elevator so no need to lug suitcases up stairs!) No AC, but we went in the Spring so it was fine with a ceiling fan and the window cracked open.
The apartment is small by US standards but surprisingly efficient. There is a kitchen, half-size refrigerator, washing machine, small bathroom, small double bed with a pullout trundle bed. Basically, everything we needed in an efficient layout. Very clean.
There are plenty of local restaurants, and she provides a list of excellent recommendations.
Communication was great - she responds to emails promptly. Check in was easy, as the keys were left at the restaurant downstairs.
