The tour was awesome but the people at the Sistine Chapel were rude and horrible. My girlfriend and I are both Atheist and still were among the only few who were respectful towards the no photography, no hats, and no speaking rules. I definitely suggest taking this because the lines are REALLY long!
A fantastic tour! Unfortunately one of the tours (maybe catacombs?) was unavailable at the time, but our guide Massimo was great! Gave us tips and places to check out around Rome and where we were staying and was a lot of fun and had a wealth of knowledge from an unbiased point of view.
