We took the Hagia Sophia tour late april with Claire. It was a super tour, well organized and about 3 hours in length. She took us through and told us all kinds of information we would have otherwise not known. And was happy to spend more time in areas where the group (4 of us) had more questions. Overall, it was a fantastic experience & I would recommend it to anyone looking for more information on the historical sites in Istanbul. I had originally signed up for a guide around the city, which to me felt like a guy who would guide me to buy things from his friends. I was very disappointed and told him so, at which point he recommended Context if I wanted 'historical' information rather than a sales pitch. He was right, you should go).
