I haven't looked at her PG for a while, but last time I did I thought she had a close to perfect body for my personal preferences.
Add to that she has some fantastic reviews on here from people who's opinions I take notice of and I certainly regret not seeing her. It sounds to me like, although she was at the expensive end of the scale cash wise at £150/h, she was also pretty near the top of the VFM list as well.
I'd rather spend £150 on something memorable than £120 on something totally forgettable.
My only problem was that she finished at 5pm every evening which didn't leave much opportunity to see her.
