Not the same agency. The one you are thinking of was 2 doors down.
Interestingly it was 2 escorts who opened Villa Gianni. One of them still runs it... the other one named Gianni has long since left the business.
Back in the day there was 3 agency's in Earls Court.
Rumor has it a huge amount of money went towards paying police off.
It's a haven for Brazilians who have no work visa and was often visited by immigration.
It used to be so elegant and beautiful decorated.
