The granny flat is in a 3 family house, which is very quiet in the Mainz Lerchenberg district. The very quiet location, however, with good motorway connections. You can easily get to the center of the beautiful city of Mainz on the Rhine by bus and tram (Hindemithstraße tram line 51, 53). They are also 30 minutes from the main train station by S Bahn. In Frankfurt am Main.
The pictures speak for themselves.
