“Excellent, and yet different from our visit to your partner catacombs below the bridge. Our guide added personal touches which made it even better. We sensed how different that part of Naples must have been, not many years ago, with the Camorra in charge. Just make sure you know how to get to the entrance. We ended up by the exit by mistake !”

It was listed as self-guided but Christian prepared the group for each stop with the history and facts a full guided tour would have. He was friendly and attentive to the entire group’s requests and questions. The 4 hours in Florence could have been done in three hours. Overall, excellent tour for the price.”
