This was one of the best tours I have experienced in Vatican City. Unfortunately, the tour guide was not present; they provided the tickets via SMS. We had to use the tickets and navigate ourselves. For St. Peter's Basilica, we were not allowed to use the skip-the-line tickets because the guide was absent, so we had to wait. Overall, it was a good experience, though I believe they might need to improve their service. Otherwise, everything was good.
