If you fancy an unusual place to stay in London this year, check out this installation "A Room for London" down at the Southbank Centre.
The boat/room is beached on top of the Queen Elizabeth Hall, and apparently you can rent it out for the night and look out over the Thames for around £120. Invited artists also use it as a studio space once a month. The work is by Fiona Banner and David Kohn Architects, commissioned by Living Architecture and those old faves, Artangel.

I think there are still bookings left for the second part of the year. Could be fun!
