Located in Chaia, this is a great place to base yourself for exploring Naples with the metro nearby but also get down to the harbour and nightlife of Naples. Federico is extremely communicable, and is a good guide for Naples. Chaia and Naples was one of the friendliest places I visited in my trip as well and there's a really, lovely local vibe that you'd expect, amidst the relative salubriousness of the area. Great time. Great place.
