Atakan was an excellent tour guide. He was extremely knowledgeable, punctual and communication with him was fantastic. We did not have to find our way on our own to the Sultanahment (Old Town) area. He met us at the port and picked us up and returned us via the subway. We spent the day learning history and seeing the historic landmarks. We stopped for a delicious Turkish lunch and concluded the day with some shopping in the Grand Bazaar. Atakan was kind enough to help me locate some specific items I was looking for in the Bazaar. We could not have me more please with our tour and guide. We highly recommend Atakan and would definitely book another tour with him.
