First of all, I would like to thank Caroline and Philipp. The owners are very friendly, willingly helped me with all the questions I had.
Perfect location, 5 minutes walk to U-Bahn. Comparatively quiet by Kreuzberg standards (however, it depends on your neighbors).
Very stylish apartment, very “Berlinish” but for many people who prefer classic design it could be not that cozy. Also note that there is no wardrobe at all, in winter it could be a problem to hang a coat.
For me that was not a problem, but there is no elevator, and for someone those stairs could be too steep...
