Located directly on the water, this romantic, relaxed and comfortable restaurant is decorated with wooden furniture, old lamps and ornate picture frames. Simply put, Freischwimmer is a cool location in Kreuzberg’s Flutgraben area. The restaurant is in a very old building that was once used for renting and repairing boats. The entrance is directly next to Berlin’s oldest gas station. You can sit outdoors during the summer and indoors during the winter.
