My roomate stayed in a long-term hostel for six months in London this summer. He really liked it. I'm emailing him for the name of it. I think its about 80pounds/week. I'm not sure if they have daily rates and this info might be useless if you're not staying for a week. I'll keep you posted.
"There is nothing in the world more helpless and
irresponsible and depraved than a man in the depths of an
ether binge, and I knew we'd get into that rotten stuff
pretty soon." - Raoul Duke
