We recently toured the Vatican with When in Rome tours. Chiara was our guide and she made this one of our most memorable tours to date. It was refreshing to have a guide feel such passion and have so much knowledge about the city she grew up in. Our 3 hour tour quickly became 4 and yet it seemed like half that time. We had 20 in our group and she remembered everyone's names. Because we visited shortly before the pope was to give his last Sunday sermon, the Vatican was very crowded, yet she managed to maneuver us between other tour groups so that we were able to spend time enjoying the arts and enormity of Vatican city. We would strongly recommend When in Rome tours for anyone visiting Rome for the first time. There are many guides outside the Vatican waiting to take you on a tour but they are not authorized tour guides so beware of this. Be sure to ask for Chiara at When in Rome Tours...she's amazing!
