I should have mentioned this before (it was late!), but I think #1 is your best layout b/c of... Workflow, (Yes, it would be better to have refrigerator --> Sink --> Range, but only if you have a Prep Sink or you don't have a DW. With only one sink, the DW gets in the way of that arrangement, so this is better) Logical separation of the major zones, Easy access to refrigerator & MW for both kitchen work & snacks, No zone-crossing, and Protection of the Prep & Cooking Zones from through-traffic in the kitchen. Note that even though the refrigerator is farther into the kitchen, it's a straight shot to get to it from the LR, table space, or bedroom areas...and no interfering with work going on in the kitchen! I know you have an OTR MW in your layout, but to be honest with you, I really do not recommend one. They're usually very ineffective hoods b/c they're too shallow and b/c they're just not designed that well as a hood (they're real purpose is a MW, venting is more of an afterthought) They're rather short for a MW (at least my sister's is...but she has a very, very tiny kitchen and had no other place for a MW, so she's stuck with it) They're not the safest things to use b/c they're so high and you have to reach up and over a hot range as well as steaming/splattering/smoking food. If you're short or a child, they become very dangerous b/c you're either reaching inside above or at your eye level or you're using a chair to get to it. Try taking a dish full of water (use cold for safety!) out of a shelf that's as high as an OTR MW is...unless you're incredibly well-coordinated, you'll have trouble blindly reaching up & in and then blindly pulling it out while keeping it perfectly level and perfectly "calm" so nothing sloshes over the edge. Your youngest will certainly not be able to do this even when she's old enough to start using the MW. Now, imagine doing this with boiling water/steam, smoke, or high heat rising or grease splattering... If someone needs to use the MW while someone else is working at the range, you'll have a bottleneck...this could be someone who's defrosting something for dinner, cooking veggies or other dish for dinner, or someone trolling for a snack. A MW drawer, regular one mounted below the counter/on the counter/hanging from upper cabinets, or a built-in one is much safer and easier to use. [If any of you are even slightly tall, then I'd nix the idea of mounting a regular one below the counter b/c of bending over, reaching in, and pulling out...all would be done blindly for someone even the slightest bit tall. (Besides, drawers are great...you open it, look down, stir, close...all without taking the dish out! Plus, it has a "cool" factor...especially favorable with the guys!)] Pantry... It depends on the handles you use & whether you have hinges on the wall side of the cabinet. But since you seem to only have a 30" deep wall, even the hardware & hinges...

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 should also mention that on the corner of the L is our entryway (which we have plans to improve in the future but not for a year or two)

I like Manon's layout the best. In your current layout (where you just moved the furniture), pull that chair out of the corner and closer to the sofa so that people have to walk AROUND the seating area instead of THROUGH it. Please do not buy one of those combo TV console/fireplaces. They are truly an abomination. It you want a fireplace, install an electric or ventless one on the wall, add a mantel shelf that's longer than the TV and mount the TV on an articulating arm. If you don't do a fireplace, mount the TV anyway so you can turn it to watch from the sofa.
