A deluxe and giant 24-story contemporary resort on the outer edges of central Santiago, the Grand Hyatt has a sprawling garden with a large (unheated) outdoor pool and all the amenities of a modern hotel-resort, from a floral boutique and a row of glassed-in elevators to Bang & Olufsen televisions and clay tennis courts. There are three restaurants, specializing in Thai, Japanese, and Mediterranean. The three-story AKO Spa has five treatment rooms and a lagoon-style pool. Ask for an eastern-facing room on a higher floor for the best mountain views.
