I met Mia some years ago, much slimmer then and I seem to remember that she serviced like a politician, seems genuinely to be doing what it says on the tin but all the way through and after you felt turned over and are left feeling unable to put your finger on why, (even after dining at the Y). A bit like the feeling you get when the girl keeps a hand in the privates area whilst screwing you...you feel fucked and yet screwed, and not in a fulfilling way.
Hence the maybe and also probably the reason for her low prices then
I'm actually a little worried now as you're the 2nd person I've heard from recently who wouldn't recommend her (1st being the most recent FB on her profile) and I've mentioned her to another punter on this forum.
To be fair though, there has been someone who complimented her as quoted below:
She has very good reviews and I met her a couples of years ago. She was good and I wanted to repeat.
It was posted in a negative review about her (has now been moved to the info section, viewable by clicking on 'Quote from: munnezzaio blablabla') but the OP was daft as a brush who posted said 'review' because he couldn't determine her exact prices/didn't bother to and did not actually went and see her.

Isabella's review is well documented in the very same linked thread as well.
