Our group of 6 had a really great experience at Michelangelo and Beatrice's apartment. The apt was beautifully decorated, very comfortable, very faithful to the photos. The bedrooms and bathrooms were quite spacious, well furnished, etc. The location is reasonably convenient.
We were also blown away by the hospitality and kindness of our hosts. They were extremely responsive and accommodating, made us feel very welcome to Naples. Would absolutely recommend.
