I don't like the QF F showers, there's only a down spray and the pressure and temperature was a bit erratic. I much prefer BA.

[EDIT - this is incorrect, see downthread] You don't get access to QR - it's not a oneworld lounge - unless flying QR which is a shame because it's very quiet, has superb food, and very bored staff who are eager to do anything to help to have something to do. I was there a couple of weeks ago and I only had to twitch in the direction of a buffet or jar of sweets for someone to run out and try and anticipate my needs.
