Here is my first cut at your space. Rev. 1 (and btw, super-duper measurements!! kudos!). I put an approximately 11' length of sofa along the wall and since you have that short wall before the windows, I put a large ottoman type piece. I put a swivel chair in "corner" of the living space near the windows so you can swivel to converse or watch TV? maybe, or swivel toward windows for views. I put a 60" long (max. to maintain walking space to other part of the apartment) and keep it 16" deep because it will stick out 17-18 with baseboard, cords, etc. Set TV on that console. I put a 52 x 30 coffee table that would be 18" from the front edge of seating area. You could also put a small round decorative stool/table, beside the swivel chair for a place for someone to set a drink/cup of coffee, etc. Now to the dining area. To get a nominal seating for six in this area, you need a 30" wide table and you might have to have it made. A live edge custom table with metal base might be great in your space if that is a style you might like. Then in the living area, go modern and sleek. I would do the coffee table, even smaller if you wish with glass top and metal base to work with the dining elements you select. The chairs at the dining table have to be really narrow across the front seat edge. That is the big challenge. This table is 60" long and 30" wide. For every day, 4 chairs could be placed there, two on each side with the additional two chairs in the corners just to give a more open feel and help maintain views. You will need some additional lighting and a arc lamp would work well on the fireplace end of the sofa and you might want another floor lamp beside the window end of the TV console. Unless you shorten the sofa on the long wall, you have no space for end tables and lamps. So something to think about when shopping. I put a 36x16" bench in front of the fireplace for one person. The seating area will only seat 5 so total would be 6. You could bring in a chair from the dining set if needed and just squeeze folks in. Watch the size of cushions for any sectional you buy, each person needs at least 24" of space, and generally don't like sitting next to each other. Also, TIP, make sure your sectional pieces join together "under" the pieces so you don't have brackets on sides. This allows for greater flexibility in "next" house and even if you just want a seasonal change of some kind here. I'll play a bit more with this later today and see what other options I can come up with for you.

I know you said you did not want to switch rooms; but since you like the look of the sink in the bay (the outside views are awesome), it may be worth exploring. If your DH is like mine, change is hard, but he comes around eventually. Perhaps posting another thread that asks people to weigh in on the two kitchen locations with a mock layout for each might get DH to consider the possibility if he can read what others have to say concerning the positives and negatives of each kitchen location. Many people are remodeling to get a larger kitchen space by eliminating two sit-down eating spaces in their homes. Thus, If you switch the rooms, I do not think you would have to “stage” a formal dining room if the time comes to sell. The larger, well designed kitchen would be a major selling point. Keeping the kitchen in its current location does not gain you a whole lot more space for the kitchen because of the traffic patterns; moving the kitchen to the dining area gains you much more kitchen space. You gain the space for family friendly island seating, and the kitchen does not have to be in a location that “fights” with the traffic patterns of your home. The generous dining space combined with the larger kitchen space would be awesome to entertain in. One negative would be carrying groceries a tad farther but not a whole lot more. ;

Sorry for mistakes in typing, hope you understand

You might try flipping the dining room and living room areas. We think the TV might work well on the blank wall where you have the dining room. Then we might place the dining room table on the angled wall next to the kitchen. See our designs here for a few other design ideas.
