The Spa At Four Seasons Hotel Downtown
As one would imagine, you'll get the royal treatment at the Four Seasons Spa. Snag an all-day package to pair your mani-pedi, massage, and facial with sips of champagne and a dip in the pool. Considering its location in the heart of the Financial District, the oasis offers a range of treatments specifically tailored to high-powered (and high net worth) individuals. But you certainly don't have to be a Wall Street billionaire to treat yo' self like one, with customized facials from brands like 111Skin and Augustinus Bader, lavish body scrubs, and energizing IV drips.
