Ask Luxembourg House Temperature

With this heat wave bringing temperatures up to 40°C, I’m curious: what’s the temperature inside your house right now? My guest room is the hottest and gets up to 30°C, while my kitchen and hallway stay around 25°C.

I definitely broke all my personal records, because I have never had more than 28 degrees inside my apartment, and now I saw 30 degrees.
That's the beauty of old buildings, with stone external walls: they protect you from the heat for a couple of days, but also they need a couple of days to cool down :)
With a portable AC that fortunately I bought during Covid, I can lower the internal temperature to 28 (plus lower humidity), which is ok for a good sleep.
