Nina's place is sweet, eclectic, Bohemian and cool. It's small, but that's not unusual for such a great price and good location in Munich (I can verify, as I used to live in Munich) and was fine for two people; and everything necessary for a comfortable week is available in the apartment, with plenty of restaurants, cafés and other shopping very close within the neighborhood. Although it's the ground floor, there are metal shutters available for privacy and safety, so there's there's nothing to worry about there.
It was a particularly great location for me, as I was in town for business meetings just on the other side of Theresienwiese. Access to Theresienwiese for Oktoberfest, Tollwood, etc. couldn't be much better. It's also walkable to the main train and bus stations.
If I have to return to Munich for meetings in the future, I'd be happy to stay there again.
