What a superb tour. Guides were prompt and located exactly as described. We went straight into the museum. Upon receiving our headsets, the guide took fifteen minutes to explain what we would see whilst inside, and contrary to posts on this site, our guide explained that three and a half hours would barely scratch the surface of what there was to see in the museum. Her knowledge was incredible, her English superb, and she did her best to ensure every member of the group was content. The Vatican is a wonderful place, rich with beautiful art and an ambiance of grandeur and austerity with or without a guide, but her assistance quite simply made the visit. I was hesitant before booking, but ended up hiring her as our personal guide for the remainder of our trip. Exceptional value and an exceptional experience. Reports to the contrary aren't worth their space on the site!
