Just to clear up the air of ambiguity. Tina & Helen are the same person. I met her (them) a while back @ A Spa after reading reviews here about Lisa (where is she now?) Tiny sweet energetic thing, with a perky little rump. Great massage & post action.
So, if Tina, or whatever name she wants to be, & Serene are both @ Relaxing aka Grand St., they got 2 gems there for non fs options. Two different styles physically & skillfully. I've never tried any of the others, but I'm sure there some hidden goodies there too.
