Is the apartment hot in summer without air conditioning?
D'e-sta-te — two syllables, stress on the first. 'Estate' = summer.
Ask before booking if the listing does not mention air conditioning and you are visiting in summer.
'D'estate' = in summer (elision of 'di estate'). 'Senza aria condizionata' = without air conditioning. Summer heat in Italian cities can be extreme — a listing without A/C can mean sleepless nights in July and August.
C'è la ventilazione naturale?
Is there natural ventilation?
Cross-ventilation through multiple windows can cool a room effectively
L'esposizione è a nord o a sud?
Does it face north or south?
South-facing apartments heat up much more in summer
Posso portare un ventilatore?
Can I bring a fan?
Ask if you can use an electric fan to cool the apartment
Italian city apartments facing south ('esposizione sud') can reach 32–35°C inside in August without A/C. Before booking summer accommodation without air conditioning, ask about the orientation ('esposizione') and floor — lower floors and north-facing rooms are significantly cooler.
