ChelseaHart is great other than that not much that I know of. There's a bait and switch scam running from a flat just off Oxford Street near Jewsons builders merchants so be careful of that. Obviously not going to post the address but it is flat number 14 if you book something in the vicinity.
There's another girl, Alaska, now running girls from another flat in the same block. Can't comment on these suffice to say that I recently left a negative review for Alaska after which she removed her profile from AW.
