Tülay was a great host, friendly, generous, open-minded.
I had a great time in his accommodation which is very close to the Galata Tower and some art museums. The accommodation is also very well connected (metro, bus only a few minutes walk).
It is located in an old apartment in a non-tourist area near the Atatürk bridge. If you are planning to spend a few days in Istanbul, I recommend without hesitation to stay with a Istanbulite. You will have the opportunity to meet around a meal and discussions. This will bring you a rich experience that is not worth any hotel room.
