Seems ok to me. She seems from what she has written to be intelligent and switched on which is rare in prostitutes. She also looks a size 10 as advertised, she does look a bit older than 26 though, not sure if that is an issue for you or not. I also think she is possibly Spanish, maybe British-Spanish?
£100 an hour is a fair price, I don't do hour bookings with a newbie, 30 mins only, that is my personal preference. Feedback should be used a guide only, not as a bible. I agree it looks decent. There's some bitchy profile text about stalkers, I don't know if she has a chip on her shoulder or not. Overaal, there's more good than bad. I say go for it.
