The room is too hot to sleep.
CAL-da — two syllables, stress on the first.
Report this in any season — overheated rooms can be just as problematic as cold ones, especially in winter when central heating is excessive.
'Troppo calda' (too hot, feminine) agrees with 'camera'. 'Per dormire' = to sleep. This is a common problem in Italian hotels in winter when old central heating systems are difficult to control and rooms can become stifling.
Non riesco ad abbassare il riscaldamento.
I cannot lower the heating.
Report when the thermostat does not seem to respond
Il termostato non funziona.
The thermostat is not working.
Identify the specific equipment failure
Posso avere un ventilatore?
Can I have a fan?
An interim solution while the heating is being adjusted
Italian central heating systems, especially in older hotels, are often regulated at building level rather than room level. In winter, rooms can reach 26–28°C because the boiler cannot be individually controlled. Opening a window is often the only immediate solution.
