Favorite room in the house to design or decorate?

I really suck at decorating. I end up cramming everything I need into wherever it will fit. In the past I was always leery if driving the lot value up because of bills. I don’t like to use money cheats because I have in the past and the game got real boring really fast. My outside spaces end up looking like some kind of hillbilly sideshow with stuff strewn here and there. With the off the grid no bills thing I may start experimenting with actually designing a space how I would ideally want it to look.
