We've enjoyed our stay in this spacious apartment, next to the U-bahn. The house was clean and the communication with the owners generally went well. For us personally the mattresses were not really comfortable and sheets not long enough (we are tall ppl). And unfortunately there was one problem: the wifi didn't work. Only a few web pages were accessible, the vast majority of pages were not. We reported this on our second day, but it wasn't yet fixed at the end of our stay of one week.
