Sheathed in a gleaming glass-and-steel tower on the Paseo de la Reforma in the banking and embassy district of Polanco, the 189-room St. Regis may seem all business, but its central location and convenient kids' club means it's also a fine choice for leisure travelers. Inside, the decor subtly alludes to Mexico's heritage while gracefully integrating textures and restful colors (shades of gray and taupe with touches of greens and purples) throughout all the interior spaces including the luxuriously comfortable rooms and suites. The dramatically proportioned reception area and King Cole Bar, on the third floor, overlooked by commanding murals by Marc Otela, leads through French doors onto a terrace with inviting seating for casual fare (there are three full-fledged restaurants here and excellent room service as well). The only quibbles are the overly complicated room lighting system and the fact that improperly angled shower drains in the opulent bathrooms are prone to flooding. Service, including the efficient personal butler, is first-rate, but the crowning glory of the St. Regis is its fifteenth floor. Here you can exercise, have spa treatments, swim in the small but beautiful pool, or soak in one of the two hot tubs, all the while enjoying an exhilarating view of mountains from your sanctuary in the sky.
Which room to book: If you aren't splurging for a suite, the grand deluxe rooms on floors 12 and 14 with their expansive views are a fine bet. Good views of Popocatépetl volcano can also be had from as low as the tenth floor from rooms 17 to 21; rooms 19 and 20 are the ones for a view of the Castillo.
