St. Peter's Dome Climb & Sistene Chapel Combo Tour (booked with The Tour Guy). AMAZING! Our guide, Maria, was very friendly, extremely knowledgeable, excellent English, and proud to be 100% Roman. The climb to the top of St. Peter's Basilica was challenging, but worth every step as the view of Rome was breathtaking. Being Catholic, the Vatican and especially the Sistene Chapel, was a very moving and sacred experience. Highly recommend this tour.
