We really enjoyed our stay at Fabrizia's apartment. There are quite a few stairs to climb, but it was worth it when we stepped out onto the terrace to see the view over the neighborhood and Vesuvius in the distance. The apartment was super clean, with AC in both main rooms (a savior in the middle of summer). I'd recommend following the map Fabrizia provides for getting to her apartment from the train station; It is much easier than using google maps. The train station is about a 10 minute walk. You can walk from the apartment to the Teatro San Carlo and the Royal Palace (20+ min walk), or just catch the bus or a cab nearby. Fabrizia was a wonderful host, giving us some great tips for where to go around the city, and ordered us a cab when we needed one on short notice. Would recommend for the traveler looking to be in the city!
