I spent 12 nights in Ananda's place, quiet a long stay, and I was more than satisfied with it. Ananda kept the genuine spirit of Airbnb : she does not only host you in a comfortable and quiet big flat - which is not so common in Naples, for the quiet part, I mean -, but she is also ready to share with you her very good tips about the town, its good adresses, its shortcuts... She is very openminded and always ready for a good conversation if you want to. Your liking of Naples means something for her and she will do her best to make you understand and love her city.
Her home is really close to the center - 10 mn by walk - and the Castel St Elmo and the Certosa of San Martin are only 5 mn far, by funicolare.
A very good adress, hosted by someone you will remember.
