The Guerlain Spa at the Waldorf-Astoria opened their 14,000 sq. ft. haven just last January, and it's every bit as luxurious as their beauty line. They offer fully customized services, starting from scenting your foot bath and linens with the Guerlain Paris fragrance that matches your personality. How? They first ask you if you want a scent that's bold and assertive, or soft and discreet, and then ask you to sample a few different fragrances that fall under the category of your choosing. Massages and facials are done only after you fill out a questionnaire and have a brief consultation with the masseuse and facialist about problem areas so they're prepared to focus on those target areas as they loosen and detoxify.
The only drawback here is the price tag - but if you can drop a little more than $500 for the two-hour treatment - it's worth every penny.
