The flat is located in a very convenient area.
You can reach the city centre within 15-20mins by trams (within 1min walk) or S/U Bahn Schoenhauser Allee (within 8mins walk). There is a huge shopping mall (with a rooftop beach bar called Deck 5) and cinema next to the S/U Bahn station.
You can also walk to Mauer Park within 10-15mins and enjoy the sunshine there. On Sunday there is the super famous touristy Flea Market and karaoke performance.
