Excellent tour. My tour guide was Luca. He knew everything about everything. We got to see so much of Vatican City. Worth every penny I spent on this tour. Only thing I'd suggest for him is to be a little more friendly and to start the tour with a little Welcome speech and ask people where they were from and stuff. Those first 5 minutes of a tour are really important. But other than that I highly recommend this tour.
The tour was wonderful, but I had to ask at least 6 people where Viator tours meet!!! There was no sign stating Viator. I found out you use a local tour company whose name has nothing to do with Viator!! It was very difficult since there are hundreds of people and multiple companies meeting in the same place!
This tour was well worth doing. No waiting in line for two hours in the hot sun! Our guide was great, our group was small maybe 14 and we saw what we wanted to see. After three hours we were mentally exhausted and needed some coffee to recuperate. Recommended - but beware, you may be in a small group but there will be LOTS of people. The vox earpieces worked a treat.
