Katherina's flat is a wonderful base from which to explore Munich. I'd suggest getting a bike for the duration of your stay. It makes everything so close. We went all the way from the top part of the English Garden to the flat with no problem! The neighborhood is quiet but there are a few wonderful restaurants nearby (a fun Greek place called Paros, a Japanese place with Bavarian charm called Nomiya, and a trendy Germany place on Haidhausen named Spezlwirtschaft as well as Classic Bavarian cuisine at Gaststätte "Zum Brünnstein"). If you have a car, leave it at the park and ride in Messestadt Ost. It's only 3€/day, 15 min via subway to the flat, and it will be safe in a garage until you leave town.
