The map is very handy, thanks. I printed it and used it on my recent trip through Naples. OP, the shops around Chiaia -- Marinella, Cappelli, Attolini, Finamore, Rubinacci, Milord --really are quite close to each other. Cappelli can be a bit tricky to find, as it's located on what is, in effect, the back side of a palazzo. But ask around, it's worth the visit.
