OK, so I am 30-something woman with great although sensitive skin.  I love the quiet atmosphere of the Nava upstairs retreat on La Cienega.  I booked a 2 hour custom facial and I will never go anywhere else again because the entire experence was fantastic.  I parked right out front (this is a private spa) and Nava is lowkey but clearly a genius of some sort because the results from the organic potions she prescibed are simply outstanding.  A+
