Two sofas, one floating to give the feeling of an entry hall. Place a long runner at front door.

Put t.v on the wall opposite your front wall picture window.

There is no fireplace, so do something extra special and make it a feature wall.

Great inspiration photo for your mid-century style. Everything works for two sofas.

The other end of the room, where the front closet is, needs no furniture, but wall decor to the left of closet door would add some interest.

love the long runner idea too.
