It is walkable from Highbury and Islington tube, mebbe fifteen minutes, but your best bet is a 341 or 73 bus from Angel Islington. The 341 takes you basically outside, and the 73 takes you to Newington Green, which is two minutes walk. If you're coming from Sarf London, and I'd love you to, then get the 21 from London Bridge or further up the line.
