Few weeks ago I've found the cheapest and very close to O2 place to sleep in London.
Campus Accommodation @ Queen Mary University in London. Single private rooms starts from 27 euros. I figured it's about 40 minutes walk from O2! I haven't been telling about this, cause I booked it just yesterday. I was afraid it's gonna be full after this post. Well, we'll see. For me it's the best cheap room you gonna get.
