A few years ago I read an easy Italian reader short story that included a great description of a young couple's exploration of Naples (the man was a Naples native showing off his city to his new girlfriend). That story inspired me to want to visit Naples and really get to know the city. I visited last year for 4 days and enjoyed it but want to keep going back.
Now my sister is heading to Naples as part of a longer trip in Italy, and although she has been a few times, she isn't really excited about the city. I'd love to suggest stories/books/movies etc that might inspire and excite her. She has traveled to Italy many times, enjoys spending time in one place for several days, staying at small family run B&Bs or renting apartments. She likes museums but is not likely to last more than a few hours. She really likes to explore the less touristy areas.
Any recommendations for how to get inspired to love Naples would be much appreciated.
