We had an excellent stay in Istanbul in Cafer's appartment. It is walking distance to the center of Beşiktaş, but still in a quiet area. The appartment was clean and well equipped. Cafer is avaialble at all times, and give good instructions and advices. The area is noce and quit, even if it is just a short walk from the Besiktas center. The apartment is very good value for money, I have absolutely no concerns recommending this appartment.
