A round or square end table big enough to provide useful space for both sofa and loveseat would work, with a large lamp. I have a couple of live plants under a similar mini-split ac unit and also near hear registers and they don’t seem bothered as long as i don’t let them dry out. Some pillows that pull the color from the very pretty rug would be nice, maybe the pink? Or green?

Drapery panels can often make the difference between a comfortable room and a cozy room that feels finished IMO. You might want to check out curtains in linen or cotton from Ikea or Target, they’re quite inexpensive and look decent for the money. Mount the rods near the ceiling molding and have the drape just barely touch the floor. You may have to shorten, they make iron on tape that make it easy to hem without needing to sew. A cream color would look nice with your gold-beige walls. Mount the rods wide enough to push the drapes back off the glass for maximum light and views when they’re open. You may never need to close them as you have blind for light and privacy control.

hope this helps.
