On the corner of Post Office Street or Post Office Road. Its behind a used post office on the main shopping road. There is a large exterior staircase leading up to an unlocked door on the 2nd floor. Only problem is that it is opposite a bar with a large glass front, so you are easy to spot. Also te car park to the old post ofice is used by people who use/work at the bar. Maybe an early Sunday mornin to get in. Had a scout round but still yet to go in.
