Naples is one the most beautiful cities in the world but not exactly laid out for tourism. Still - if you come here to relax, you should take day trips to the islands in the gulf of Naples - Capri, Ischia, and Procida. The water is crystal clear, the restaurants are excellent and the islands themselves are just beautiful.
Quick Tips:
You should learn some Italian before you come here because most people won't understand any other language. Plus: The better your Italian is the better you will be treated and the less people will try to make you pay double when you buy things, take cabs etc.Best Way To Get Around:
Public transportation is OK in the inner city but not recommended for long distances. There are buses and subways, but you will wait a very long time for them and they will be very crowded. If you come to Naples in your own car, make sure that you still have it when you leave - if you know what I mean... Besides: People in Naples drive very fast and don't respect red lights. If you take a cab, make sure that you have an idea about how much you will be charged for the trip - just to avoid surprises.
