Cihan is such a kind person and a wonderful host! Apparently, it's true what people say about the great Turkish hospitality. It was a pleasure to stay with you and to spend talks and dinners with you, my dear friend.
I spent one month at Cihans place, which is close to my university. There is a metro station 15 min away from his tidy apartment and there are many busses departing right next to Cihans home, so that guests can explore the beautiful neighborhood Moda, which is part of the district Kadıköy, and other parts of İstanbul of course. During nights there are Dolmuş and taksis that bring you home even from Taksim, so don't worry about being far from the city center.
Cihan has an incredibly beautiful view of the city and the sea from his apartment, so that you can watch the sun set and don't even have to leave the house :D.
Besides, there are many supermarkets and shops around his place (which you can assume due to the neighborhood's name Küçükbakkalköy, if you speak Turkish, I guess).
To sum up, I warmly recommend everyone to stay with Cihan.
