My flat mate is going to be in Berlin/Russia till September. The flat is in Manor House, literally 2mins walk from the tube and there are loads of buses going all over, so great transportation links.
I'm not 100% sure on exact dates but it's roughly from 26th June - 21st September.
It's a small double room & it's only £80 p/w. So very cheap. There isn't a deposit, only a weeks rent up front & then ongoing till you leave.
We have wireless & a large, shabby garden which is ok for BBQ's. We're right on the edge of Finsbury park & Clissold is only a 10min walk.
If you're interested or know anyone who might be, PM me.
