I have seen comments about Sophia somewhere on the web, on other forums. She only offers massage according to her website, not full service. She's quite pricey, and I recall one review said it was a very sensual experience. However I don't think she offers B2B according to her website, and may not even allow you to touch her. This is just the impression I get from various sources, as well as her own site.
If you decide to see her it would be worth checking with her what she actually offers, to avoid disappointment.
