I finally got a chance to see Sylvie. The previous posts are all pretty accurate. She's a cute, polite Milf with a great ass. Massages in a thong. She's not particularly warm or oozing with sensuality, but she gets the job done. I took half an hour and I think that's the best deal with her since she her massage while light and pleasant doesn't vary at all until its time for the flip and then an HJ which while not exceptional is better than average. At $40 for the half ($60 full hour) she's a better deal than most parlors and independents.
I will repeat if I am in the area (Pie IX and Fleury).
