My experience also. I was not only disgusted at the b+s to someone so old but also the place itself was a total hovel not fit for habitation. Actually never seen anywhere like it after hundreds of punts.
Sounds like you went to the exact place too... I met her at a dark entrance which looked like it belonged in a horror movie. I didn't go further as I could tell she was too old. She looked kind of surprised I walked though, so I think someone manages the AW page for her. She did look like she had a nice body, so they should just be upfront with what's on offer.
Have you had any luck exploring these B&S profiles? This one wasted about 1.5 hours of my time between texting, walking, and taking the tube, so it's a bit discouraging.
