Remède Spa at The St. Regis

Sitting on the 15th floor of The St. Regis Mexico City, this spa pulls off the rare trick of combining skyline views with actual quiet — rare when you're this close to Reforma's traffic. The space includes a sauna, steam room, and indoor pool, all kept impressively clean and not overly crowded even on weekends.

Therapists here know what they're doing — the personalized massages and hot stone treatments get consistently strong recommendations, and they start on time. Remède Spa won Mexico's Best Hotel Spa at the World Spa Awards. Show up early to use the facilities before your treatment, and note that spa access isn't automatically included with a massage booking.
