I clean my room three-to-four times a week. I can't stand it being messy for more than a day. I start spazzing, and then I must clean it. I don't like having a mess.
Same for most of my apartment, except for the kitchen. In there, messes are made by my roommates who..more often than not, don't clean them up. So, I make them clean it up, clean it myself, or my boyfriend cleans it.
My boyfriend, actually, COMPLETELY cleans my room. When I say I clean my room, I take most of everything off the floor, kinda my nightstand..but he does a LOT. It makes me feel very grateful :)
