When cracker and backpage were around, there were some legendary private operators that ran out of 1 or a few apartments with a few girls on weekly rotation. Prices were at $150/hr, and there were some bangers that came out of these shops with fantastic service. PCD nowadays is a bit of a throwback to some of the apartment set ups, though they charge more than the average brothel.

I haven't had such luck with brothels, then and now. They may have the odd good performer, but majority aren't great.
