Cihan is a really really great host. Everything was perfect, we went just after an attempt at Ataturk airport, and Cihan had great advices for us.
He helped us to organize our trip and we loved his "joie de vivre" and his good mood.
The flat is nice and very well located, near Istiklal Street and not so far of the center : it is about a 15 minutes walk from Istanbul's historical centre.
