The flat was as described: very clean, light, well-supplied with all one might need for a short or longer stay, well-heated, quiet, and at an easy walk to underground or bus stations. Our host was very helpful and accomodating in all ways.
For those who need an immaculate stairwell and entryway, this is the wrong neighbourhood; for us a certain 'Kreuzberg nonchalance' was no problem, and again, the flat was all we needed for a comfortable and affordable vacation.
Thank you to our host.
