Neighbour to one of Italy's most esteemed music conservatories, this erudite bookshop fills with the sound of practising musicians. Most new and vintage-edition titles are in Italian, though English-language titles include Colonnese's editions of Neapolitan-themed classics. You'll find quality original and reproduction Neapolitan prints from the 18th and 19th centuries, as well collectible postcards from the late 19th and early 20th centuries.
Note that during quieter periods of the year, the shop may close for a few hours at lunch or on Sundays.
