Tips from locals
If you do not fear dark and narrow places, please go and see this staple of Neapolitan culture, a guided tour in which you the guides lead you into the belly of the ancient underground city.
It's the underground city (search on google). We have a really old underground city under your foot. You must go and visit the underground city in Naples. It's one of the most important things to do. One access is really close to my flat (in piazza San Gaetano).
