      What about San Pietro is unique but much of the credit goes to the guide, a Roman girl (sorry I don't remember the name) who was able to give the right taste to everything, with historical information and curiosities. The kids, in the age group between 7 and 13, got involved and had fun. The times of the excursion are correct. Well done and thanks for the great experience

      Our guide was very knowledgeable and detail-oriented. Got to learn more about the symbolism inside of the dome, look at the major works inside (+great explanation), walk up the stairs to the top and have full-overview of the city skyline, as well as the underground floor. The whole tour took 3 hours (instead of 1.5-2), however, if you are booking multiple Vatican tours for the same day, make sure to have 1.5-2 hours between the sessions, otherwise might get a bit overwhelming:)

      The visit to the basilica is totally worth it! I have already traveled to many countries and seen a lot - the inside of St. Peter's Basilica took my breath away! The rather long climb to the dome also rewarded us with a spectacular view of Rome! Sensational! If you don't mind a lot of steep stairs, you shouldn't miss this experience !!!
