The Romanian tradition of eating a teaspoon of honey begins many of the treatments at this massive, elegant oasis (where a 60-minute massage costs $190). Amenities include a rooftop garden and one of the city’s only Watsu pools (the water is warmed to match your body’s temperature, and a therapist massages your floating limbs). Clients are encouraged to spend an entire day unwinding in the bevy of rooms—including the healthy in-house café and the relaxation library, which offers comfy couches and cashmere blankets.
