With names like Azalea, Magnolia and Lilac, treatment rooms at this elegant spa are all about organic luxury. Start your visit with a trip to the sophisticated locker room, which features a cedar sauna and private vanity areas. From there, try the Aroma-Tonic Body Envelopment ($145), which begins with a full-body exfoliation and finishes with a clay and papaya cream mask to soothe dull, dry skin (perfect if you’re here during the harsh winter). When the weather is nice, be sure to slather on the SPF before heading to the sun deck, where terrific views of the neighboring John Hancock Center make you feel like you’re on top of the world. And considering the level of service you’ll find here, it’s more or less true.
