As an old local to Istanbul, I can confirm that Ugur's place was excellent. The location is perfect to visit everywhere in the city, especially if it is your first time. Uğur meets all the requirements of being a good AirBnB host and goes beyond it. His place is very clean and well decorated with industrial design touches. He is very communicative and provides you with local tips to avoid tourist traps. I would highly recommend his place for a good Istanbul experience. Also the roof is fantastic :)
