Stefano is a very helpful host. I stayed in his apartment for 6 weeks and the location was perfect, two blocks away from Bergmannstrasse. I consider this the nicest area of Kreuzberg. Lots of restaurants in the area, and my favorite Alnatura and Bio only few blocks away, the two bio/organic markets in bergmannstrasse. Every weekend there is also a flea market in the area. Only two blocks away from the ubahn. Very convenient.
