Absolutely awful! Would never recommend someone stay with Saban. At every turn he was unprofessional and sketchy. My girlfriend and I didn't feel safe or comfortable doing business with him.
The place he put us was not the place we rented, as other reviewers had mentioned.
He then went to move us to a new place on our last night with him, and we had to drag our bags for 15 minutes through the streets of Istanbul to a new place. When we arrived, it was filled with smoke and the place was so dirty. I immediately had to make an emerged hotel reservation so my girlfriend and I wouldn't be out on the streets with our luggage.
Do not rent from Saban if you want to feel safe, taken care of or like your host is responsible. Also, pay a little extra and rent a hotel in the same area - I can't explain how much better our stay was for just an extra $30 a night above Sabans place.
Don't rent from Saban.
