A small scale (apartment sized) 3-seat sofa and two chairs will serve you well. Don't corner any furniture or TV. It shouts that you don't have room for your furniture in your home. Scale is what will save the day. Think low and sleek, not big and boxy. This includes a credenza for the TV to sit on. Sleek and skinny seating Minimize arms Keep the pieces low and sleek

end table with storage and slender shelf unit

So I re-read your wishes for the room, and also noted you are near the beach as well as in the rustic woods, and want a cozy entertaining nest. Here is something that might work for the wall at the end of the stairs this table Put a mirror over it and at the end of the table nearest the stairs, put a striking structured plant like a bromeliad. Position a small dark-ish circular rug under this table, big enough to be a landing for whomever is coming down the stairs. If you want cozy conversational in the rest of the room, consider low modular sofas, and if you want swivel chairs, stick with something low profile and add boho foot poufs and textured lumbar pillows try a simple textured rug on the floor or something in a very low key tribal pattern. Think of twigs and branches when it comes to end tables. If you want to embrace the staircase, maybe artfully arranging these behind the staircase would be fun Put in one or two of these for books and low seating with lighting and pouf for a secret reading corner

@Maddy Jens congrats on the house it looks beautiful! I grew up in a 1929 bungalow with no formal entry. Your new space looks like there may be room for an entry to the right as you walk in. A bench (with storage) below the window and a thin profile console table with mirror on the wall to the right of the opening to the dining room? The fireplace seems to be the focal point of the room. Keep a couch with or without chaise add-on on the wall and perhaps round coffee table with two chairs facing the couch? If you need desk space that could go where the rocker is now, against the wall perpendicular to the fireplace wall. Beautiful house! Enjoy making it your own :)
