Any suggestions on best seats to Maldives for a couple - other half thinks the view dictates better to get two window than two middle - he's probably right

We're on BA 77W and the seatplan on the app has the galley and toilets between rows 18-19:



Whereas https://www.aerolopa.com/ba-type-77h has it between rows 7-8 (From which I understand that 77H is uniquely identified as 77W on BA's seat chart).

Does anyone know which is correct - I'd assume BA knows how they've configured their plane?

Also any recommendations on seating for a couple, side of plane, or anything else for the Club suites and/or Maldives would be very welcome
