That's pretty nice actually!
I am in a brand new rooftop apartment, so pretty exposed to heat. I can keep 28-29C indoors when it's 38C outdoors. That's hot but workable with a ceiling fan.
At night we open all windows and have a ceiling fan above the bed. We've got about 24C indoor in the morning, with nightime outdoor temperature at about 21C.
Obviously I keep physical activity to early morning and late night.
We also have high humidity which makes 25c to 30c at night very uncomfortable for us Brits.
People often forget about humidity when telling people they don't need AC
And you have to remember we're a country of people used to max summer heat mostly being around 20-22c and many people will sleep with the window partly open in the depths of winter
True that it is not so humid here in the French alps.
But to be clear: do get an AC if you need to. Please dont rely only on your AC though. Turning on the AC (eg just pressing a button, really) is so easy we tend to forget about the rest... and end up burning even more fuel.
