Good stay in the flat. Nice quiet neighbourhood in a good location. Pasing in not in the town centre but has a great shopping arcade and excellent connectivity via bus / tram / train to the city centre.
Sanna let me use her bikes which is ideal as its a 25 minute cycle right into the centre of Munich. There is also a good beer garden within 3 minutes of Sanna's place which is nice to get a bite to eat, a bier and mingle with the locals.
I didn't meet Sanna as I delayed my arrival but her communication was first class and she sorted out entry to flat even though I arrived on a very popular German bank holiday - great service.
If you don't want the noise and bustle (and lack of parking) of the city centre when you finished your day, this is a very good option.
