Fantastic place to stay in Istanbul when you have to catch a flight from Sabiha Airport. This place is one metro (M4) stop away from Sabiha Airport. Flat is located in a very secure building, and the host speaks very nice English and guides you well. The area around the house has too many restaurants to eat food, shopping points, and grocery stores. This area is cool and calm in the night and has a lot of things to offer in a day time. The only thing you need to do is bring your own towel as it is not, which somehow makes sense. Other than this, yousuf is very good host and his house is pretty clean I would recommend to stay at his place 100%. Good luck with your bookings.
