I had many Airbnb stays in Istanbul but my stay at Damira's place was the most comfortable and even the cheapest. It was my first time to stay at a shared apartment ( private room ) but I had much of privacy. She gives you a lot of space but makes you feel at home. She even cooked and left food for me while I was working. The room, sheets and blankets were also very clean.
I would recommend the stay and will definitely come back.
