A warm-toned rug on wood floors sounds like where you are headed eventually. On the way there,I would consider a leather sofa with enough depth to be snuggly (Article's Sven model might work with its tufted bench seat) on the solid wall and a couple swivel chairs. Or maybe, a couch with a chaise on one end (Houzz heresy,I know) and smaller scale chairs. And, most importantly, the tables (or maybe an ottoman) and lamps needed to make the place comfy. Where else can I put down my Jameson's and my book? Right now,that fireplace wall seems to hold one end of your space,the kitchen cabinetry the other, and not much of interest in between. Once the focus comes off that fireplace wall, it will lose that prominence. Especially with some art over the couch and drapes at the window. You may still wish to change it, especially the mantel, but maybe not.
Now,if you want better advice from some of the talented folk, post a simple sketch with the measurements of the space. Until you decide, here's a pretty pic or two....wherein somebody forgot to paint the wood!
