Not really in line with "i Silenzi di Napoli" (LIT The Silences of Naples) though it's quite an immersive experience, approaching Piazzetta Olivella (very close to the Montesanto stop) you will go through a flock of pigeons, making them fly away (they'll have their revenge as one of them will shit on a friend of mine). Then you'll stop by a book selling stand, skim through a few books, hear the conversations of the seller and of the various travellers and occupants of Piazzetta Olivella. A very fun and dynamic experience.
