Flying IAD to LHR on an A350 as a couple in May. I'm 6'5" so booked 1D/1G for now because of the reported larger footwells. I know the window seats in row 1 are considered very desirable but they face away from the aisle. Are the middle seats which face the aisle equally desirable (far less is written about them)? I can't tell if facing the lavatory is a big issue on an overnight flight. Trying to balance leg room with quietness--there are still a lot of middle seat pairs open to choose from. Thanks for any advice!
