We need to see more pics from different angles, but from what I see so far I would take down the picture from the wall by the window. It looks squished. Perhaps you could center the loveseat under the window with the table and lamp in the corner.

Do you need that amount of seating? If not I would remove the extra sofa by the door and place one or both chairs there and center the sofa on the window wall. Or if you prefer to lay down while watching tv take away the chairs and line both sofas up facing each other.

it is a charming house!

I would maybe use a wall mount for the TV and add just floating shelves to store TV electronics. Something like this there are many floating wall mounted TV consoles that I think will allow you to better off center your tv and give you the cleaner lines you are after.
