I stayed there for one night in January, it wasn't bad and they give you free breakfast. I rode the 29 bus to Finsbury Park which took 10-15 minutes.
Arsenal Tavern Hostel £6 a night. Bit of a schlep to the ground though. It must be at least 800 yards!
I have a pair of tickets for both days available if anyone is interested. Soome friends from Slovenia are not coming over now. Drop me a line should anyone want to take them up.
