Sorry this is so late! I was in Istanbul a year ago and did a tour with Hanifi and it was amazing! Hanifi is a warm and caring person-the perfect type of tour guide. He took me to the Blue Mosque, the Grand Bazar, the Galata tower and showed me part of the old and new city. He structured my tour to the sites that I wanted to see and to my time frame. He took pictures of me and made me feel welcome in Istanbul. If I ever return to Istanbul I will definitely be calling him for another tour!
