Can you keep my luggage for me?
'Custodire' — 'cus-to-DI-re'. Four syllables; stress on the third.
Ask at a hotel reception when you need to store luggage before check-in, after check-out, or while you go sightseeing.
'Potete custodire' uses the second-person plural of 'potere' + 'custodire' (to keep/safeguard). 'Il mio bagaglio' is 'my luggage'. Italian hotels universally offer this service — it is considered a basic hospitality courtesy.
Posso lasciare la valigia qui fino alle tre?
Can I leave my suitcase here until three?
States a specific time limit for storage.
Tenete i bagagli dopo il check-out?
Do you keep luggage after check-out?
Confirms the post-check-out storage service.
Il deposito bagagli è gratuito?
Is luggage storage free?
Most hotels offer this free; some charge for long periods.
Italian hotels ('alberghi') always have a concierge or reception service that stores luggage between check-out and departure. In Italy, this service is expected as part of hospitality — it is almost never refused. Always get a luggage tag ('etichetta') for your bag.
