This was the first tour of our trip with Gianni. It was very well done. We had 3 kids with us (3, 8, 10) and Gianni kept them engaged. The kids especially liked the Bridge of Sighs and the prison. :) He was very patient with my daughters' questions and obviously very knowledgeable about the locations. If you can manage to book a tour with Gianni, you should do so. We had 14 people in our group and it was great!
