I had a great stay! Arnd was always reachable and very helpful. The apartment is much better than it is on the photos, more space, very clean. I had a long stay and the kitchen was all equipped to cook. And the bed was really comfortable. The area is perfect; it is on a quite and safe street so never had a noise problem but it is walking distance to lively Kreuzberg area. Also the transportation is very close. And if you need a break the park just next to the apartment is a great space. I would recommend this flat to everyone.
