Karin & her son were very welcoming and helpful with directions, wifi etc. Karin's home is the perfect location to experience Oktoberfest. It really is just a 10min walk and very easy to find from the S Bahn / U Bahn station. My boyfriend & I arrived in Munich on a public holiday so no shops were open. Karin very kindly let us use her toothpaste which we'd planned to buy once we arrived, she also gave us a plastic carry bag for some clothing I needed to take with me to Oktoberfest.

All in all it was a very enjoyable stay, definitely recommend!
