Our guide was very knowledgeable and had a great sense of humour. The Vatican museum was impressive and pictures of the Vatican just don't do it justice. The fast track system that you get with the tour is well worth the money - we beat all the queues.
Marco was fantastic! My boys, ages 12 and 10, found his 6 1/2 hour tour interesting, informative and really really fun! We will definitely hire him again when we return to Rome and I will recommend him highly to everyone I know!
