Dear Judith,
I am glad to read that you're going to spend a month in Naples and its surroundings. I will be very glad to help you, although I am not staying in town between April 2-15, due to some conferences my boyfriend and I are going to attend In Spain and Tuscany.
Starting from April 16, anyway, I am sure we can arrange a meeting and a couple of trips around town and outside.
I think it'll be easier if you mail me directly at pmaturi@hotmail.com
Yours
Pietro
p.s. if you prefer me to use Italian, just say so. ciao
