Lucio was there to welcome me and gave me accurate directions, as the address does not show up clearly on Google maps. He provided lots of materials re sites in Naples and also breakfast and water (for a small fee). The apartment is ideally situated a short walk from Toledo metro and via Toledo, as well a 15 to 20 minute stroll from the archaeological museum and the seafront. First timers shouldn't be intimidated by the Spanish Quarter – its bark is worse than its bite and I never experienced any problems. Enjoy this vibrant, crazy city.
