Good spot there by Prof Yaffle - those pics are by a well known glamour photographer so she's obviously a professional escort but they will be heavily photoshopped so don't expect her to look quite so flawless.
I think the options are:
1 - She's not the sharpest tool in the box and cocked up one of the listings to get the wrong Sandyford.
2 - Sites like Backpage and Vivastreet vacuum escort listings off other sites to boost their ads and make it look busy because they haven't many for that city - but they could have cocked up the geography.
3 - An ugly munter has stolen her pics because they look much better than hers.
Personally I think it's probably 1 but as ever in this game buyer beware and if an ugly munter does open the door be prepared to walk before you hand over any cash. You can always use the 'I left my wallet in the car excuse' or if it's obviously not her just say you were expecting to see someone else.
But photoshopped or not don't think you will be able to mistake that body if she's genuine - let us know how you get on!
