We stayed for one whole week, 3 guests. Karam was very friendly and helpful in helping us with the directions to the apartment.
The room itself is b 3 people to enjoy themselves, and also really cozy and tidy.
Thanks to this housing, our trip to Berlin was really wonderful, as there were absolutely no problems in coming or going whenever we liked, no problems with his flatmates, thanks again, I can only highly recommend staying at Karam's :).
