If you just have a few days to spend in Naples, the ideal spot to stay is in the historic center.
You’ll be in the heart of things to see and do, and you’ll find many b&b’s and hotels that are less expensive than in areas closer to the sea.
And you’ll also be able to quickly reach the metro stations at Piazza Dante, Toledo, and Materdei stops.
If you want to stay in Naples’ historic center, I suggest the “[Santa Chiara Boutique Hotel”](https://www.booking.com/hotel/it/santa-chiara-boutique.en.html?aid=7961984&no_rooms=1&group_adults=2&label=where-to-stay-in-naples
