As cities go, Naples isn't for the faint-hearted. The bustling streets are buzzing with beeping scooters and lively locals. It's as stereotypically Italian as a city can get, and that's what's so charming about it. Plus, it’s the birthplace of pizza, and tucking in to one here is par for the course. You'll find pizzerias everywhere, including one which is among the oldest in the world.
