We mostly have tiles everywhere in the house. I have f.ex. laminate in my 3 bedrooms, like you said, it's not as cold as tiles. But usually you put rugs/carpets around to make it warmer.

I remember when I was a kid, that at that time there were also still carpets in every room, but it's just so unhealthy, especially for little kids crawling over it and inhaling all the dust.
