O serviço de quarto fica aberto até 23h.
When a specific hour follows *até*, the contracted form *às* is preferred in formal Portuguese.

Cultural Tip
In Brazil and Portugal, hotels usually give hours in the 24‑hour format and contract *a* + *as* to *às* before the time. Saying “até as 23h” (without the accent) is considered a spelling mistake. Also, “serviço de quarto” can refer both to food delivery and to housekeeping, so context matters.
