FWIW, I've lived in small apartments...Big apartments...single wide trailers...small houses...large 2 storey  house (now). Small places AND large places are hard(er) to keep clean and tidy . Small ones because unless you're a minimalist everything is crowded together so it's hard to keep clean (because you have to keep moving stuff around to clean one area, move it back, apply lather rinse repeat) ; big places just because there's so much to clean so it takes forfreakinever. The easiest places to keep clean are medium-sized apartments and houses : Space to spread stuff out , but not so large a place that it's automatically going to take forever.
