We did a self-guided walking tour of this city that came recommended by Rick Steves, the travel writer. We loved it. We walked through the Spaccanapoli and shopped throughout the Centro Storico. We had a lovely lunch of authentic Naples pizza which was absolutely delicious! We purchased some Limoncello, which is a must in this area! The lemons are huge and delicious. I was worried about some of the stories I had heard about the dangers of the city, the petty thefts especially. We had no problems at all. We didn't dress flashy or carry large bags and we were totally fine. This is certainly a city we would return to for a few days.
