Apparating to Grimmauld Place

I was wondering how Hermione managed to bring Yaxley (I think it was him) from the MOM back to Grimmauld Place when she Apparated them after they retrieved Slytherin's locket from Umbridge.  The reason I ask is that GP is under a Fidelius Charm and Yaxley didn't know the address. Shouldn't he have been bounced off or something.  In canon it had never been the case you could just take someone there by holding their arm, or Apparating them, say, from the park across the road to the front doorstep.  They ALWAYS had to be given a slip of paper with the address on it before they could see the building and enter it.

Just curious,
