Gokhan and his place were amazing. He met us at the Airbnb, letting us park our car in his garage and showed us the place. It is very close to a "5th Avenue" street full of upscale shopping and a 20 min walk through a park to the ferry for Buyukada and other Princes Islands. Very nice neighborhood and safe.
He was gracious enough to come help us get in when we were having trouble, but fortunately we got in! As there wasn't a guest the next day, Gokhan was even so kind to let us keep our big luggage while we went to Buyukada for the night. His place felt like home and you'll never find a better host. Definitely stay here!
