Ours were modest: half a duplex, a one-story rancher-style, a 3-story townhouse, and they were never immaculate. The floor and furniture was covered with dog hair. My room in the rancher was a wreck, but when we moved to the townhouse, I had to keep much tidier, because my room was 10x10. I didn't even have a desk in there and did all my homework on the bed.
