Front of the bus on the right hand side 1K+2K are usually our preferred seats on a 343. 1K is next to the lav, but has the compensation of a flat triangular shelf which is useful for newspapers, empty champagne glasses and other bits and pieces. Both face the wall and require you to talk over the partition, not a big deal if one of you sits on the ottoman of their seat.

By the way, zone B (the mini cabin just in front of PE) is best avoided as there is too much cabin crew traffic.
