Last i heard was two biz class type fold flat seats behind the cockpit. The galley and shitter would be the same as in a 737 as it was too expensive to design a smaller galley vice just using the one that's already there. It should include the same microwave seen on 737s, which if you haven't used it - F'ING ROCKS! Something that takes 5min to cook takes 45sec-1min.
So, it *should* be comfortable. But i am sure within approx 1-2mo of delivery it'll smell like stale farts, overcooked pizza pockets, and spilled lubricants (not THOSE kind of lubes, you sick bastards - this isn't the VQ version).
