PLEASE do yourself a favor and book Valentina's space for your trip to Naples. While it is a little outside the city center, it is only a 12 minute walk from the metro station, and the funicular can take you either up or down some of the large hills on the area. It is located very close to Castel St'Elmo(13 minutes), where you absolutely have to hike up the steps to get a gorgeous view of ALL of Naples.
Valentina was EXTREMELY accomodating, and provided us with quick responses recommendations on things to do/where to eat in the area. The house was incredibly clean, and Valentina even let us stay an extra few hours after check-out since ourtrain came so late. When i come back to Naples, I will stay with her again!
