I just messaged them to make an appointment and was quoted 500 roses ! Is she really that good ?
It depends on how you define value in a p4p context.
If you fantasize about dalliances with women who have engineered their bodies in a way that is ostentatiously sexual, then $500 may be more than reasonable. However, if you're of the ilk who undervalues physical appearance, and instead prioritizes service and performance, then whether you pay a $60 street walker, a $200 AMP gal, a $500 AAMP gal, a $1200 independent gal, or a $1500 pornstar - sex is sex with enthusiasm and engagement being highly variable across the respective categories.
Some guys will balk at $500. Other guys will shrug their shoulders and conclude business as usual. I consider myself as someone who is not easily impressed by p4p gals, because I over index on physical beauty, and 97% of p4p gals spanning the gamut of AMP to Indy don't quite match up...but in Gabriella's case, although Vietnamese gals are not a preference of mine, I'm convinced that even at the $500 price point, she's slightly underpricing herself.
Studies have concluded that most untrained people cannot distinguish between a $25 bottle of cab sauv and a $250 bottle of cab sauv. Contrary to popular belief, women are not like wine. Physical beauty plays a large part in the quality of any sexual experience, yet smaller than life guys continually delude themselves into believing that physical beauty is but an afterthought.
This is all to say that you won't be disappointed by Gabriella's physical beauty - although, again, I can think of 4+ gals that I've met through p4p who I would consider more physically attractive than her.
With respect to performance, I excluded explicit details from my review, but rest assured that I thoroughly enjoyed my time with her.
