This is a great appartement with a stunning view over the bay of naples, we used to have dinner on the balcony. (bonus: you can access the roof where the view is even more spectacular). The apartment is spacious and well equipped. It's about 15 mins walking distance from the center. The only downside is that there's no AC in the second room, just a fan (2 units out of 3 expected) so one of us had to sleep on the sofa in the dining room. It is really a problem if you come during the hot season, otherwise probably not.
Overall we had a wonderful experience and I would do it again.
