Mehmet was an amazing tour guide. His knowledge of the sights and the city/regions history was vast. He spoke as though he was telling an engaging story, which helped hold the attention of our two teens. We had only an afternoon to enjoy the city and we were able to see all the prominent spots. He was patient with us and answered all of our questions. We are already talking about our next trip to Istanbul and we would absolutely reach out to Mehmet again. The transportation was clean and air-conditioned and incredibly comfortable. We had a fantastic time.
