Not only does this quietly elegant downtown hotel have one of the best hotel spas in New York, it boasts one of the best spas in the city, period. Both Greenwich Hotel guests and New Yorkers flock to Shibui Spa, a tranquil and elevated space that includes a heated, indoor pool, relaxation lounge, traditional Japanese soaking tubs, and steam and rain showers. Treatments include everything from oxygen facials to full body exfoliation to onsen bathing rituals.

And while we wouldn’t blame you if you spent your entire honeymoon in this superb spa, the whole of the hotel is worth exploring. Definitely don’t miss a meal (or three) at Locanda Verde, chef Andrew Carmellini’s hearty Italian restaurant, or a drink at the guests-only, relaxed Drawing Room bar. And we must give special props to the staff here, who are known throughout the city for their unobtrusive, yet rigorous dedication to guests.
