Rocker pations used to late-night recording sessions and impromptu villa debauches can partake of facials by Arick Odaka, the sure-fingered azstbetician responsible for Hilary Swank’s spotless skin, and body treatments that use Erbe, a line of organic botanical blends whose creator trained under Umbrian monks. For post-massage blissing out, head up to the gem-like rooftop pool.
