Your hotel checkout is at 11am. Your flight is at 9pm. That's 10 hours of dragging a suitcase over cobblestones. Or: €5-8 at a luggage storage service and 10 hours of freedom. Every Italian city has luggage storage — at train stations (KiPoint/Stow Your Bags), near major attractions, and through app-based services (Bounce, Radical Storage). Train station survival →
Roma Termini: KiPoint (underground level near platform 24) — €6 first 5h, €1/h after. Open 6am-11pm. Also: Radical Storage (multiple locations near Termini, Colosseum, Vatican — €5/day via app, book online). Firenze SMN: KiPoint (platform 16 area) — €6/5h. Bounce/Radical Storage — near Duomo, Santa Croce, €5-6/day. Venezia Santa Lucia: Stow Your Bags (inside station) — €6/5h. Also: Piazzale Roma (ASM Venezia, near bus terminal — €7/day). Venice is the WORST city for luggage — bridges + stairs + no wheels = nightmare. Store bags BEFORE exploring.
Napoli Centrale: KiPoint (ground floor) — €6/5h. Milano Centrale: KiPoint (arrivals level) — €6/5h. Bologna Centrale: KiPoint near platform 1. App-based (any city): Radical Storage (radicalstorage.com) — partner shops (hotels, cafés, shops) near attractions. €5-6/day. Book online, show QR code. Bounce (usebounce.com) — same concept. Nannybag (nannybag.com) — same. All insured against loss/damage.
Rome Fiumicino: Left luggage T1+T3 — €7/5h for carry-on, €11/5h for large bags. Milan Malpensa: Baggage storage T1 — €8/day. Venice Marco Polo: Left luggage arrivals — €7/day. Pro tip: Train station storage is CHEAPER than airport storage. If you're passing through the station anyway, leave bags there.
