My wife and I had a 6 hour personal tour with Hanifi. It could not have gone better. He spoke perfect English, which makes absorbing the important facts much easier. We were picked up at the cruise ship port in a new comfortable mini van with a dedicated driver. This allowed us to be dropped off with the guide in front of the sights. We toured Hagia Sophia, Blue Mosque, Basilica Cistern, and Dolmabahçe Palace, which was substituted for Topkapi since it was closed on Tuesdays. We can't imagine that Topkapi is any more grand than it. As a certified tour guide with many years of experience, Hanifi was able to provide interesting facts of each location. You will be very pleased selecting Hanifi as your guide in Istanbul. He will tailor your tour exactly as as you desire with the time that you have.
