Hakan was a great host. He answered a few queries I had before I had by email with good advice (especially on the cheapest way to get to his place from the airport) and very helpfully arranged a taxi for me to get back, essential in a city where taxi fares can be quite fluid. We shared a couple of meals together and had some good conversations, yet my privacy was always respected. His apartment is very comfortable and located in a nice neighbourhood, with lots of stores and cafes, quite close to one of the ferries and with buses nearby, and not too far a walk from the tram that runs into the other side of the city where Hagia Sophia are located. The room was well appointed with thoughtful touches like a bathrobe and slippers. I had a great time and would definitely recommend Hakan's place to those visiting Istanbul. Thanks Hakan!
