A long overdue update:
I'll put up a proper photo soon.
Lighting, the rug, and the bay window are still to be sorted out. I'm very happy with the new layout. The apartment feels bigger, there's more walking space, and it's a great setup for hosting friends.
The optimal rug would be 7'x11' and since that size doesn't really exist I'm resigned to getting a small rug that will fit between, but not beyond, the couches.
@Jr Mouse, we picked up six spare folding chairs...
