Sorry everyone, I'm pretty new to this site and don't really know what's what.
Here's the how it went down:
I text her on the day for an appointment on the same evening and I got a text back saying it's all fine, time, post code etc. I arrived and went into the flat and it was someone who, in my opinion, looks nothing like the pictures. She was a very friendly Russian (just like the profile said) and had brown/blonde hair. Her body is certainly not as toned as the picture of her in the gym suggests, in fact quite far from it. She's not overweight or anything, but certainly not someone who goes to the gym often - and not what's alluded from the pictures.
I'm not sure what else to say...
