As a person who moved to Spain (Barcelona though) from Sweden, I agree. Houses here have basically no insulation what so ever, unless they're built recently. During the summer, it's almost impossible to escape the heat unless you have AC inside. Meanwhile, in Sweden you can usually just enter any house and can be sure that there is at least is a temperature difference compared to outside just because of way better insulation.
