Rosina was a nice, warm-hearted and thoughtful host. My arrival time was very late, but there was no problem to check in at all. The room looked the same as the photo and very clean. I stayed 5 nights there, and we had chats almost every morning which I enjoyed. She even gave me some information which only locals would know. :) Also, she was flexible on the time for check-out (as there was no guest on that day). I felt like home!! Thanks Rosina, her family and roommate for all the things!!
Another strength of her place is location. Her place is near some museums and philharmonic concert hall, also it is very easy to go to other places in Berlin.
I won't hesitate to choose her place again if I come to Berlin next time.
