Levent, our tour guide was extremely informative and this made the tour very enjoyable. I had only booked for the 1/2 day tour, but I paid extra and joined the group for lunch and a tour of the Topkapi Palace. A visit to a leather factory turned out to be a sales pitch in a showroom. A visit to a shop was a sales pitch for carpets, although the staff did not pressure too much. Overall, an enjoyable experience.
