We had great days at Kamuran's flat. The flat was neat, clean, and cozy as expected. The location is superb. You reach Taksim square by 5 minutes of walking. Istiklal street with many eating, shopping, and entertainment options are all available on foot distance.
Kamuran was friendly and responsible. He responded within minutes (or even seconds!) every time that I wrote him.
I strongly recommend this place.
