No need for googling, we here in Peshawar even know the areas where they have rented bungalows and operating in connivance with govt's support
Ive seen them myself back when the PC was not bombed, They initially stayed in the hotel and the ISI was after my father for permission to bug the hotel rooms. It was clearly refused, blackwater or not, they were the hotel's guests and that would never be compromised.
Eventually they looked for a more permanent residence, usually in University town area.. rarely in hayatabad.
Most of them however, were used to provide external security for Consulate members, sort of an on call crack team.
