“We started the tour at exactly 2:05 PM. It was incredibly interesting, and I found it exciting to walk through the narrow tunnels. My husband, who is claustrophobic, was accommodated well since there are larger tunnels that can be used as bypasses. Our guide, Giulia, was extraordinary. I would rate her a 10 out of 10!”
