If your goal is entertaining, then I would definitely recommend the mirroring, 3 cushion sofas if you can fit them, and then (swivel) chairs at the end facing the fireplace. Make sure there are enough surfaces for drinks and food, and if you have space to tuck extra ottomans underneath a sofa table or console, that allows you modular seating you can use at a moments notice!

Okay, I'm going to take you at your word that you're actually asking for input. Also assuming that you're in the process of… what? building? finishing this space? A long space that is brick all around will always be lacking for light, so any way you can get light into this place. Also with a long narrow space that has to work as both living/dining will need you to set 'zones' and create a visual divider. Lighting will be crucial. Create a conversation space, a dining space—and with the door opening directly into the room, don't put any furniture immediately so as to create an entry space (although a credenza or narrow table against the inside wall would be good for keys etc.)

If teal isn’t doing it for you that blue color is really pretty too and still would look gray with brass and the grey floor tile! I found a few good options on amazon for the hardware by searching brass square pulls and also these on way fair: https://www.wayfair.com/Hamilton-Bowes--Ventoux-5-Center-Bar-Pull-24128SB-24128SCOP-L1123-K~HMBW1035.html?refid=GX293766718941-HMBW1035_40348394&device=m&ptid=762818256643&network=g&targetid=pla-762818256643&channel=GooglePLA&ireid=83020192&fdid=1817&PiID[]=40348394&gclid=EAIaIQobChMIsbjP3fmW5AIVgrfsCh1oWwbcEAQYDSABEgIS_PD_BwE Here is a link to a similar light fixture! https://www.bellacor.com/productdetail/elegant-lighting-ld6042br-eclipse-brass-and-frosted-white-12-inch-one-light-pendant-2116486.htm?partid=googlePLA-DataFeed-Pendants-2116486&kpid=2116486&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_-All_Products(NEW)&utm_term=&utm_content=multi-converters_(2-5)&gclsrc=aw.ds&&gclid=EAIaIQobChMIv_64qPqW5AIVFKrsCh0HGQGgEAQYCCABEgJyK_D_BwE I think the subway tile will look classic and gives you more leeway to get a countertop that can be the star! If you picked the geometric backsplash I would say go for simple very toned down counters.

Oh to respond, the rug is 9x12. It hits the fireplace, feels big in the small area. But I see what you mean. I do agree with switching out some end tables.
