Round tables from what I’ve gathered take up less space so I’m not sure why a 58” diameter would be too big, but a 72”x42” would fit properly. I think either would look fine and also laid out a 70x30 ruffly measured table, honestly I preferred the round and felt I had more space.

Hello so we have a open living room, dining room and kitchen with wood floor we trying to get the transition on the color on the walls with the rest of our living space so we’re not changing anything else the furniture stays the color in the kitchen floor everything stays good just need to create a warm and cozy transition to the whole living area thank you Adriana

I don’t have opinions on all your questions but I do think the stone coffee tables are too flash, and wood is the way to go. I think you don’t need a dining room rug. It helps keep the space feeling airy to have the bare floor. Get a simple console. Maybe you‘ll want to reupholster your dining chairs someday, but I see no need to replace the whole set. Get rid of the torch floor lamp. If you want art upstairs put a big piece on wall of the upstairs hallway. Don’t put it on the overhang between the windows and the mezzanine. I never like gray, but that’s up to you. I like the present color of your rooms. I tend to like to do something unexpected and unique in decor, so I would be thinking about painting a slightly different color (or wallpapering) that one part of the ceiling that is the underside of the mezzanine balcony. In the end, I might decide against it. But it’s tempting to wonder what might be interesting and pretty as an accent

Nothing. It's the only breathing space in the room between the dog beds, cabinet, mirror, dining table, corner cabinet and window console table. If you feel compelled to fill that space, take the pictures on the hallway wall (that you can't enjoy because there's no light anyway), reframe into coordinating colors and hang in the open space which will then leave the hallway wall as breathing space to the next area of the house. Maybe remove the items, on top of the cabinet below the mirror, to steady the visual space.
