My wife and I spent 1 day with Nilay Cagli Turkeli last October. She is in her early 30's. Very knowledgeable about Istanbul and Turkish history. We did a walk through the back streets of the Grand Bazaar, seeing a couple of artisans at work, but unfortunately several were not working that day. Visited the Mosque of Suleyman the Magnificent where she pointed out alot of details I did not recall from a guidebook. Also took the ferry to the Kadikoy neighborhood where she lives and ate lunch at a local restaurant away from the touristy waterfront area. We let her know about some of our interests and she organized the day as to what to do first, when to meet the ferry, etc. It was our first full day in Istanbul before we met the RS tour, and we believe she provided a good introduction to Turkey. We also enjoyed her perspective as a young female living in a predominantly Muslim country.
