Could I have an extra blanket?
'Coperta' — stress the second syllable: 'co-PER-ta'. 'Potrei' — stress the second syllable: 'po-TREI'.
Use when the room is cold or the bedding is insufficient. Simple, polite, and resolved quickly by hotel staff.
'Potrei avere' = 'could I have' — 'potrei' is the first-person conditional of 'potere'. Using the conditional is softer than 'posso avere' (can I have). 'In più' = 'extra/additionally'.

Combined request
Italian hotel rooms, especially in winter, can be cold if the central heating is not working properly. In Italy, buildings often switch heating on and off on fixed dates (usually 15 October to 15 April), regulated by local authorities. Outside these dates, radiators may not function even in cold weather.
