I absolutely recommend the Hotel Piazza Bellini & Apartments if you are visiting Naples. We upgraded to an apartment with a rooftop patio after we arrived, and we were so glad we did. It was really nice to have a kitchen and living space (and two bathrooms). The room was beautiful and clean, and the view of the piazza (and Vesuvius in the distance) was fantastic. It's also a great location, just blocks from the Port'Alba and Dante Plaza, where there is a metro station.
