They've had the one 1 pound room/person for the last couple of promos--if they find more than one, they'll cancel both, so just sign up your SO or travel companion for the second one.
I got one of these earlier in the year and love the hotel--here's a link to a blog piece I wrote w/photos and info about transport, neighborhood, etc. (scroll down to the bottom of the page). The piece above it is about Hakkasan, London's much ballyhooed (unjustly, IMHO) Michelin-starred Chinese restaurant. Enjoy and good luck on 10.4!
