Have to agree that wall mounting the tv is probably your best bet. Do you have plaster walls? I can't tell how old the house is from your pictures. Fishing cables through plaster walls can be difficult. However, there are cord covers that you can use to cover the cables on the wall. They can be painted to match the wall color. And if you Google a bit, there are a lot of creative ideas on how to hide all the tv cables out there. I'd do a bit of research first, to get the wall mount that will work best for you, and to figure out the easiest way to hide all the cables. If you don't want a rug, and I don't blame you, those floors are sure pretty, think about doing something else to help "furnish" the room. I could see a large plant on the wall with the tv, or a bookcase for display. I think if you can find something else for that wall, in addition to the tv, it will make the room seem more fully furnished.

Try a 3-seat sofa facing the windows with a coffee table and two chairs, one at each end of the coffee table to form a "U." Use a drop leaf table behind the sofa to serve as a dining table/sofa table.Hang art opposite the grouping with a console or credenza below it. On the large wall add casegoods (bookcases, a secretary, display cabinets.) Additional art between the bedroom and entry doors. Scale is different below, but just for concept of a "U" and of a sofa/dining table.

Thanks all again but after being in the space and testing out the layouts your offered, I really do prefer the TV in the corner so I'm trying to decide between one of these 2 corner TV stands: https://www.birchlane.com/living/pdp/pullman-corner-tv-stand-for-tvs-up-to-65-b001030194.html?piid%5B0%5D=1082005253 https://www.birchlane.com/living/pdp/birch-lane-heritage-benedetto-corner-tv-stand-for-tvs-up-to-65-b000771980.html Thoughts? Then I can put an upholstered storage bench underneath the big window and a console/desk behind sofa with chairs for extra seating. And I still want to get a chaise lounge or armchair with ottoman place counter the sofa (empty space in mock up below). *Mock up is not the right colors or styles but just picked based on size to help with figuring out layout

Agree with lynartist get someone knowledgeable in to look at the walls. Shifting the color used makes a huge difference. I would not have the walls smoothed or made shiny. But there are all sorts of ways to approach this and end up with a great looking home. Consider moving the functions of the two spaces. A modern dining area with a fireplace, even such an ornate one, could be spectacular and marry well with a more intimate USED space for conversations, drinks, and even just solo book readin'! Making the switch would also de-emphasize the fireplace and allow it to look its very best. A bit of a paradox but look at many old European houses and you'll see it again and again. My other preference would be to have a wood refinisher take down the shine on the floor. Congratulations and I hope you let us know how this progresses.
