I spent a week in Johann's flat and I can't find anything to complain about my stay. The apartment is just a stone's throw from whatever you need: restaurants, shops, cafeterias and, of course, public transport. You can easily reach any sight, attraction or landmark in 15/20 mins using either the U6 bahn or the Badner bahn. I don't need to spend a single word about the flat: just take a look at the pics: is exactly what you will find. The furnitures smell new and the most of the equipment is still unused. The district is quiet and the building is silent. Johann is kind and communicative, ready to answer in a while to any request. Definitely recommended.
