Thanks to Pelin and Koray for hosting. They are very conscientious hosts. Koray provided directions to the taxi driver and met me on arrival, and he checked in throughout my stay to make sure everything was OK. The flat itself is perfect for a visit to Istanbul. It's not a five-star resort, but has everything you need (and more), the price is right, and you don't want to spend your time inside anyway. The location is ideal, as advertised. Would absolutely stay here again.
