Knowing that this the only room on the first floor, now I understand why you have a bath there. It's nice that guests could use the bathroom without climbing stairs (and that you can, too, while you're working from home in the home office). I think the tiny sink on top of the toilet is pretty ingenious, given the space limitations - I've never seen anything like it! I'm not a pro, so please take my thoughts with a grain of salt (or a heaping spoonful): Squeeze as much of your bedding as possible into the closet. If it doesn't all fit, consider getting a storage ottoman or bench/chest and squeeze the rest of the bedding into that. You could use it as a footrest for the couch most of the time, and then tuck it alongside the far wall as a nightstand when the pullout bed is extended. I like the idea of mounting the TV opposite the current couch position on the wall. Then you could see it from the couch/bed. Are all of those paintings just possibilities you are temporarily resting there? The space will look less cluttered if you get rid of some of them, and if you hang them properly on the wall rather than leaning them against it. Consider getting a white fan that will blend in with the ceiling. The current wood color of the fan blades doesn't go with your floor, and I think it makes the room look smaller. Find a spot for the lamp elsewhere in the house. Edited to add: Consider getting a rug in soothing colors; something with cream like your walls, taupe/brown like your couch/floors, or a soothing accent color (soft green or blue?). I'd avoid a bright bold pattern like your current rug, given the limited size of the room, and that I generally desire my office and bedroom to be calming spaces.

Personally, I'd dump the floor lamp and put a small lamp on the night table instead; replace the desk with a small dresser; add blinds or curtains; and hang some art for a bit of color. I'd also think about a small chair in the corner where the lamp is. I think guests would be pretty comfortable with the result.

I like your rearrangement. Now for suggestions.....The coffee table is too big. I would like to see a round ottoman there. I would put your little mirrors around the bookcase...three to each side. Get a end table with lamp for the end of your couch nearest the dining room. Maybe a tall plant on the other end of your couch. To soften the room, if you want to, I would get some sheer curtains for the windows Also I would pull your sectional out away from the windows...looks sort of shoved in. Pretty dogs.

I want to add a door to make the small den as guest room. What can I do with this ceiling😰 Anybody have any good advise. Thanks！！
