I know this post a rather dated, although I would like to add my realitively recent "NEGATIVE" experience with Welsh Katrina. Unfortunately, I didn't know about the existence of this website, so I fell into the trap.
She is definitely not the one shown on the photographs on both Adultwork or Backpage UK (or maybe she was a good 20 or more years ago). She is, I guess, on her 60's, and she lives in the Caerphilly's area. She is a rather abrupt lady, not pleasant to talk to, and her services are appalling: I mean really no skills, no thrill. She will not let you touch her hair (she goes mental if you do), no kissing (which I can understand) and definitely no different positions in bed; she will try her best to harry you up to your orgasm and then you are out. She gave me a "massage", which I would rather call it a rub, then a below average oral, to finish off with her riding on top of me. Once I was done and dusted, in less than 15mins, she left the bedroom and she went downstairs in the kitchen. This lady really knows how to make you feel uncomfortable. She is however a fairly good looking mature woman with enhanced breasts and if she advertised what she is really like, and maybe pretend to be a little more accommodating, she would really make some money as many would find her a real turn on. In conclusion, I would personally dissuade anyone from wasting £70 for much less than an hour (it all depends on your stamina) of a mechanical process that has very little to do with a sexual intercourse with a rather rude lady.
