Can you explain how the room telephone works?
spiE-gar-mi — the 'ie' is a diphthong, say it quickly.
Ask when checking in if you want to know how to use the in-room phone for internal calls (reception, room service, wake-up).
'Può spiegarmi' (can you explain to me) uses the modal 'potere' in formal 'Lei' form + indirect pronoun 'mi'. 'Come funziona' (how does it work) is an essential question phrase. 'Telefono di camera' is the standard term for the in-room telephone.
