My space is in the basement, though it doesn't have any doors, the previous owner thought it wood be nice to tear out the extra wall to make it a sitting room, though after her fire and the flooding she realized this was a bad idea. I can't complain though, I keep the floor swept, the window clean, got a nice case for my vidya and books, plus a doggo to keep me company at night.
I plan to eventually put nice wooden slats down so that it shines when you mop it, and I also plan to put up pictures that I find online and frame to give it more of a personal feel. Just one step at a time.
