Walk in the aircraft, turn hard left, and you can't miss it.

More seriously, it was a fine seat but not in a single respect any different from 3A, the only other A380 F seat I have sat in. Both of them are about as far as you can get from a lavatory/galley/bassinet position and still have a window, which is all I care about. The new F is a treat, IMO. You should have a great flight.
