Neighbouring one of Italy's most esteemed music conservatories, this erudite bookshop fills with the sound of practising musicians. While most of its new and vintage-edition titles are in Italian, you'll also find quality original and reproduction Neapolitan prints from the 18th and 19th centuries. Look out for the collectable postcards dating back to the late 19th and early 20th centuries.

The store occasionally opens on Sunday from 10am to 2pm.
