We had a great tour guide who we met with for both tours. We didn't realize we would have several hours in between each tour which was a wonderful delight! We were able to fit in a lot of other sites in the afternoon. Our tourguide had a little cold and kept blowing her nose with her microphone on which was a little frustrating, but the content and pace was great!
Skip the Line: Vatican Museums Walking Tour including Sistine Chapel, Raphael's Rooms and St Peter's
The tour was excellent and Francesca was VERY knowledgable and helpful throughout the tour. We were just disappointed that we didn't get to tour St Peter's due to the Pope's audience on Wednesday mornings. We did get to do it on our own but paid some random tour guide in the square to be able to skip the line (which was really worth it).
