Isik was great host. he helped us on everything, we arrived early in the morning and he managed early check-in for us, he gave us public transport card, explained everything we wanted, and isik also has a good information on city. he also left us until 8:30 pm in the appartement because of our late flight, and he was always near and on line to help us, so Isik was very kind to us.
Everything you see on photos works well in the appartement, wi-fi is fast. it is best situated in istanbul. there is 24 hour market, cheap bakeries, fast foods, all kind of restaurants, places to buy little presents. although in the center, the street is not noisy.
If you visit istanbul, i undoubtedly recommend Isik's house-great host, great appartement, great place.
