Volkan was a great host. He gave us many detailed information about the cheapest and fastest way to reach his flat coming from the airport. He was very welcoming and was very happy to give some tips for restaurants, bars, buses to go to historical part of the city etc... He was also very available on the phone or per email during our stay to answer questions we may have.
The flat was very clean, bright and well equipped. It was also very well located (5 mins walking to Istiklal and streets around with nice restaurants, shops and bars), 10 mins walking to Taksim square and 15 mins walking to Galata bridge via Istlikal.
I would definitely recommend you Volkan as a host and this place to stay in Istanbul !
