Fantastic studio. Perfect price for value! And worth noting: this was of the very few Airbnb flats where I have been over the last 2 years (and I went to many: approx a new one every two weeks) that was officially and in reality a non-smoking place!
In addition, Engin was always super responsive and very friendly, allowing me to enter the flat very late on the first night. I really clearly choose this flat again all the next times when I come back to Istanbul, as often as the flat is available. Thanks Engin!
