What time does reception close?
'Reception' is used as-is in Italian, pronounced 're-CEP-shon'. It is a common loanword in hospitality contexts.
Ask to know if you can return late and still get assistance. Smaller hotels may have unmanned reception at night.
'A che ora chiude' = 'at what time does it close'. 'Chiudere' (to close) is the verb. This is a standard question using the third-person singular present tense. 'La reception' stays in Italian as a loanword.

Small Italian hotels (pensioni, B&B, affittacamere) often have a 'portiere notturno' (night porter) or rely on coded entry systems. Larger hotels have 24-hour reception. It is courteous to inform the hotel if you expect to return very late.
