selcuk has 3 rooms. one is basically a bedroom. that is where I stayed and it is clean and quiet. the bed is very comfortable. it is adjacent to a full bath which is shared by the other guests. there is also a toilet room which he had the males mainly use. the other 2 rooms are larger, one with a balcony. he cleans comon areas every day. there is no use of the kitchen. wifi is good. location is a 15 min walk from the estrela hotel. metro stop are about a 15 min walk. his house rules are respectful- quiet hours, no additional guests, no alcohol smoking or drugs. after 2100 it is very peaceful. he evicted a guest while I was there for coming home drunk or on drugs and annoying another guest. I guess I slept through it. my air bnb fell through and he rented to me at the last minute and was so hospitable. communication in English in not a problem. he answers all requests in minutes. because he took me on quickly he did not have a set a keys. he always rearranged his schedule to fit mine. you will have a nice stay and learn a lot about the area and Berlin. he is a great host.
