Is there any place to drop luggage at Naples train station?
There are no lockers at train stations but most larger stations offer left luggage service. Here’s a link to the one at Napoli Centrale. Allow yourself some time when picking up luggage. If it’s busy, there may be a line.
I just returned from a trip to Italy including Naples. There is a place to store luggage at one end of the station. Cost approx US$8 for storage.
How long can you store luggage for $8 at Naples Central Station?
For each piece of baggage service fees are € 6,00 for the first 5 hours, € 1/hour from the 6th to the 12th hour, and € 0,50 for every additional hour.
