Ralph's place is really well situated next to Görlitzer Park, in an area of Kreuzberg that has great restaurants, cafes, bars and amenities. It's close to the U-Bahn, and a great spot to explore deeper into Kreuzberg and south past the beautiful canal area into Neukölln.
The apartment is perfect for one or two people, and contains all the amenities that you might need for a stay, as well as some extras like a filter coffee machine, a washing machine and a dishwasher. Although the apartment is on the ground floor, its location near the park means that it's normally a quiet and peaceful place to stay.
