We stayed at Doruk's place for four nights. I knew the area of Serdar i Ekrem from a previous stay and was happy to find Doruk's apartment with Airbnb. Doruk supplied us with detailed and good information about Istanbul before our arrival. He was there upon arrival and departure. He organized a shuttle from and again to the Airport and he helped with the confirmation of two restaurant bookings which I had already made from home. The apartment is great, quiet and very clean. Doruk had prepared a sweet welcome gift for us. We felt very comfortable even though we didn't spend a lot of time there because Istanbul kept us very busy... Thank you Doruk for everything - we appreciated.
