@Wayne146 I find your photos redundant. 3 photos of the living room, 3 of the dining table, not one photo of the kitchen, the view (if there is one) or the surrounding area, and bed looks like someone just got up out of it and hastily threw the duvet back on.
Bed- I'd get a bedspread- just something to keep the bedding clean, doesn't have to be thick or expensive. Also more pillows on the bed- many people read in bed at night and one pillow isn't enough to prop yourself up in a sitting position. They'll be taking the couch pillows into the bedroom and they'll end up on the floor. It's also nice for guests to have a choice of pillows- pillow preferences are quite individual. I have a thinner, synthetic pillow and a thicker feather pillow for guests (I only host 1 person, so they get 2 pillows).
Yes, as another host suggested, some art on the walls, looks pretty barren. The choices here are myriad- paintings, framed photos or posters, tapestries, even some good kid's art. Doesn't have to be a lot, but just a focus to liven up the space.
I also like your choice of red as an accent color, very nice.
