I had a wonderful stay at Kristin's. Her place is exactly as pictured and described - charming, perfect for up to two travelers. The bed was comfortable (important for me as I have back issues), and surprisingly fit my 6'5" frame, despite being listed as a double. The balcony was great for kicking back after a long day of sight-seeing.
Kristin is an excellent communicator and would send me messages in advance to advise if she would be without internet for a duration; she provided a back-up in those situations.
Her place is a few minutes' walk to Maillingstrasse U-Bahn, a few stops away from central Munich where many of the city's attractions are situated, but it's only a 30 minute walk to Marienplatz, and much quicker by bike (which Kristin kindly offers). Multiple grocery stores are a few minutes' walk away as well, for those who want to cook up a few meals themselves. The best thing is that it's very much a family neighborhood, so it's not particularly noisy aside from the buzz of normal daily activity. I should note that the summer weather all but requires the windows and patio door to be open, so light sleepers / later risers will want to bring a pair of earplugs to block out typical sounds of traffic, neighbors, or kids on their way to the local school.
I had a wonderful time in Munich and Kristin's hospitality contributed highly to that. I'd definitely stay again.
