It was lovely staying at Karin's apartment, and she is one of the nicest hosts we've ever had. So quick to help, send recommendations and respond to anything. The apartment is in a great location. Not in the heart of the city exactly, but 4 minutes from 2 trams to the historic center and the same distance to the subway which is a main line to connect to anywhere. There are 4 supermarkets within easy walking distance, as is the cool Yppenplatz with many cozy restaurants. We were also near Alser Straße and Lerchenfelder Straße, both of which have many interesting restaurants and cafes. Even with a month there, we didn't get the chance to try all that we wanted.
