Ahmet is a wonderful person and a great host. Always available for any support or guidance if required. Respects privacy. He is a very friendly and decent person. His place is a great place to stay if you are in Istanbul. The location is very nice and close to many key places like Istiklal street and Taksim square. Havabus (airport bus service) stop is not too far either. The apartment has all the required amenities. Strongly suggest to stay at his place.
