*Google map warning* So until Google maps fixes their issue, his address is actually really close to the train line U6 at stop Grumpendorfer Strabe (or Strasse, depending on how its pronounced). Aside from that, there is some stairs that you have to walk up in order to arrive at his place. Once inside, its great. Its actually one of the very few places with a freezer. Despite the map issue, I highly recommend this place as Dominik was a great host!
