We stayed at Franzi & Monika's for 5 days during Oktoberfest. They were extremely accommodating with our check-in and check-out times, and while we didn't use much of their knowledge for tips and tricks around the city I am sure they would have gladly provided them. We felt safe and they were very respectful of our space. The town centre is roughly a 20 minute train ride from their apartment which is made easy by an extensive metro system but besides the mall there is not much to do in the area. Would definitely recommend for a pair of friends or a couple for their stay!
