The ad is mainly a front for miscellaneous Asian women (not the one in the picture) working out of various locations around toen. Some attractive and some less so, and some providing a better experience than others. It's hard to book (you will probably wait once you get there), you will probably see other people in the apartment, they don't speak English, and they might try to upsell to a double midway through the session. The quality varies - one was literally on her phone midway through haha. The whole setup has the whiff of ethical concerns, though nothing that I can confirm. But ultimately it's not a straight up scam, if you persist you will end up with an SP, just not the one in the picture. In the end, just go in knowing what to expect
