We stayed in Leo's flat for a week and it was the perfect base for our trip to Berlin. The flat is lovely - comfy, spacious living room, nice bathroom and shower, very well-stocked kitchen. The location is excellent also - right on the canal so the views are beautiful, and lots of lovely cafes and shops just around the corner. Also, it's just 10 mins walk from Oranienstrasse where there are lots more bars, restaurants, etc, and 4 mins from the nearest U-Bahn station. We particularly liked the turkish market on Maybachufer strasse. I would strongly recommend anyone to stay in Leo's apartment in Berlin.
