This lovely hotel has so much going for it—a historic setting, a pair of fine restaurants, a fitness room, and sophisticated rooms, for starters. Relax beside the indoor pool, work out in the fitness center, or enjoy a massage at the spa. The lobby bar is a great place for a drink; if the weather's right, sit in the courtyard, where you can forget you're in a concrete jungle. By day you can readily explore the quaint antiques shops, restaurants, and tango halls of nearby San Telmo. After the office workers head home the area is desolate; it's also on the fringe of some sketchy streets. Taxis are the way to go.
