Communication with Anna was without problems, because she was in India, I was in touch with her friend and she provided me with the keys. The flat is nice, big enough for 2 persons for a short-term stay and not far from the U-Bahn. Unfortunately, the heating system did not work and although Anna´s friend did her best, the flat was cold my whole stay. As there was 9 C outside, maximum inside was 16 C and I got cold finally and spent 3 days in the bed after. I was promised to get some money back, but nothing came to my account so far....
