The apartment is located between Görlitzer Park and Paul-Lincke-Ufer which are both really great places. Paul-Lincke-Ufer is a street in Berlin running along the Landwehr Canal in Kreuzberg. Opposite is the Maybach Ufer where the Turkish Market takes place on Tuesday, Friday and some Saturdays.
Görlitzer Park is an 800-by-200 metre park in Kreuzberg with lots of great restaurants and cafes around.
You’ll have everything you need in the flat. Very good internet as well.
