If you're looking for someone similar to Charntelle, who actually provides the services listed, then you might be on to something
I hope you've read the 3 reviews on here that appear below your post - 1 positive, 1 neutral (mine) and 1 negative - not a good record, and in hindsight I think mine should have been a negative, but I was fairly new at the time.
Don't be mislead by her AW feedback, much of that is for other services, like chat, and the escorting stuff is probably bollocks, like a lot of AW feedback.
So, in a nutshell, don't bother with Charntelle, but if you can find someone like her that does what her profile claims, go for it
