Fodor's Expert Review Casa Calma

This "wellness hotel" in the heart of downtown Buenos Aires has taken the concept of in-house spa to a new level, equipping each of its 17 rooms with jetted tubs—six deluxe rooms also have saunas where you can relax after a day of exploring the city. The vibe throughout this boutique property is eco-chic, with lounge chairs crafted from recycled fabrics and wood floors made from sustainable pine. Sleek bathrooms feature all-natural soaps, bath oils, and gels, as well as towel-warming machines and plenty of room for candles, chocolate, and champagne. An "honesty bar" lets you help yourself to juice, wine, and sweets.
