I hate carpet, bought a new one 18 mo ago, now it looks really grubby (mind you bright/darkish red is a good colour to go for, doesn't show too much) and I would have floorboards like a shot if they were still under it - sadly it's been cemented long ago.
But that means no mice which is good.
New flat has nasty 70s carpet in the living room, can't wait to investigate what's under it...though might be shocking condition of course.
Laminate is nasty, we have it in ds bedroom which is good for setting up trains etc and any spills or sick incidents, (though they have always been in my bed so far ) but it is slippy and cold. It was here when we came.
Wood every time - it ages beautifully, even when knocked and walked on and so on. Everything gets worn but wood wears it well
