To the OP: Don't overthink this. I have travelled several times in C on TG B77W to/from CPH and there is not much difference between the seats - the A/B and J/K seats at the windows are great for a single traveller. The middle seats are great for 2 persons travelling together. The difference between e.g. 11B and 12A is minimal, so pick any of the A/B or J/K seats (if you travel alone) and I'm sure you will be satisfied. The galley is in the front but when in 11B I was not disturbed at all. You will be fine in 15K. All BB77W C seats are great.
No wifi on B77W.
