Cultural Tip
In Brazil most large hotels offer 24‑hour room service, but smaller pousadas may limit the hours. The expression ‘por dia’ is the most natural way to say ‘per day’; ‘ao dia’ is also heard but sounds a bit more formal. Remember to keep the article ‘o’ before ‘serviço de quarto’ – omitting it sounds unnatural.
