Rosaria's apartment was fantastic. It is larger than it appears in the photos, with an eat-in kitchen, two separate living areas, and a terrace with extends along two sides of the apartment. I was there in June and so made great use of the terrace, day and night, and the air conditioner was helpful.
The apartment is right in the centre of Napoli and Rosaria was a great help with information and ideas that only a local would know.
Worried about noise from the famously lively Napoli night scene? With the windows closed all is good (and I'm a light sleeper). Also, being on the top floor makes the place even more tranquil as there is not a lot of traffic from the neighbours.
I would stay there again in a heart beat.
