There is no toilet paper.
i-GIE-ni-ca — four syllables, stress on the second.
Call reception or press the service button. Toilet paper should be replenished daily by housekeeping.
'Manca' is from 'mancare' (to be missing/lacking) and is used impersonally — 'it is missing'. 'Carta igienica' = toilet paper (literally 'hygienic paper'). 'Manca' is incredibly useful — use it for anything that is missing: 'manca un asciugamano' (there is no towel), 'manca il sapone' (there is no soap).
Mancano gli asciugamani.
There are no towels.
'Mancano' is the plural form — used when multiple items are missing
Manca il sapone.
There is no soap.
Basic amenities should be replenished daily
Non ci sono ciabatte in camera.
There are no slippers in the room.
Slippers are standard in higher-category hotels — ask if missing
Italian hotel housekeeping ('servizio ai piani') typically restocks amenities during the daily room cleaning ('riassetto della camera'), usually between 10am and 2pm. If you need something outside those hours, calling reception is always the right approach — never hesitate.
