As a female solo traveler I can say the area is great and pretty safe, you're very close to the old city but not in it, which gives you some quiet and space, with no one to make noise at night. My room was spacious with a sweet balcony I liked and the entire space was nicely furnished and designed by Massimiliano. He was very sweet to help me with my bag and point out local points of interest around Napoli. When I needed to contact him he replied quite rapidly and explained everything nicely. The place felt homey and nice. Definitely enjoyed my time there, grazie mille!
