I live in Sweden and there is very heavy insulation, however it makes it unbearable at the end of the summer days (sunset around midnight). I am lucky my current place the bedrooms get the morning sun, not the afternoon sun like my old place.

In my old place I would often sleep in the living room sofa because of the heat.

Our place is more like your old place: all the bedrooms get the afternoon sun. We usually relied on having the blinders (external ones, electrically actuated) down, keeping the bedrooms dark until sunset (and using the external cool air at 7AM to cool the house for ~1.5 hours). It still doesn't solve the issue completely, the interior air temperature sometimes gets to 29-30 Celsius in the afternoon.

A bit on the toasty side. That was before we had solar installed, now we might as well get AC to use the sun to our advantage. On a personal note, I like the interior a bit warmer, somewhere around 24-25 Celsius.
