I would highly recommend "What a Life Tours" for anyone who plans to visit the Vatican/Sistine Chapel. The entrance to the site is an ordeal to navigate without a guide. I usually pride myself on managing on my own. It was such a luxury to be escorted by our guide, who kept us entertained throughout. Guiliani was very well versed in the history and current events of Roma and VC, and he had such respect for the art. He prepped us for the security check in, which was quite chaotic. Once inside, we spent time discussing the artwork so we could enjoy our experience. Although it was busy inside the Vatican museum, he expertly guided us to the important exhibits. Well worth booking this tour!
