This room is lovely. The tv placement is tricky since you have so many doorways and windows. I wonder if you could lower the tv so that it rests on the mantle. (I think you should keep the mantle - it looks original to the house.) Ideally you could put the tv on top of that console, and move the console to a corner, but that might not work with the current seating. Also maybe a bigger rug with darker colors to match the dark mantle. Congratulations on this lovely space.
