I've been asuming he used Shrieking Shack tunnel all along, and took 
recidence in the place where Lupin used to be during their 
school-days. Not many people were likely to come as only RL, PP, SS 
and AD knew how to calm the Whomping Willow, of them PP is one he 
wanted to catch, RL could be convinced about PP and he *is* a 
friend (he might come during full moon, if SB knew he was at 
Hogwarts), AD and SS are too busy with their jobs to come... It's 
*the* safest place for Sirius to be, with an easy, safe access to 
Hogwarts!
