This is an excellent tour and I cannot believe I forgot the guides name he had a heavy eastern european accent This tour allows you access to many parts of the catacombs that are off limits to the public. I do not think I would have enjoyed it without the tour as the guide gave so much background to the history. After a while you realize it is just a graveyard, but being in a tour added to the experience. The line to get in is crazy long too, we skipped in front of people who had been there 1-2 hours. They can only let in a certain amount of people at a time. You definitely want to pay for the tour and skip the line, worth the money.
