Translation:
Hi there. Yes, I live in an apartment—a living room and bedroom totaling 50 m²—facing northeast.
It’s a concrete building. We had thermal insulation work done three years ago, but it protects better against the cold than the heat.
I bought a portable air conditioner, but it doesn't actually lower the room temperature; it just blows cool air, which is still something, at least.
The price of houses near Paris...

I don't even want to think about it!
I imagine older houses with thick walls stay cooler.
Good luck to you—I dread the thought of it starting up again here; for now, I can finally breathe.
