The Spa at Four Seasons Hotel Philadelphia at Comcast Center

The Spa at Four Seasons Hotel Philadelphia is perched on the 57th floor of the Comcast Center and is the city's first and only Forbes Travel Guide Five-Star spa. The space features over 700 pounds of healing crystals embedded in the walls, creating an extraordinary sense of calm from the moment guests step off the elevator. Reviewers consistently describe the ambiance as world-class, with panoramic city views, tranquil relaxation lounges, and impeccable attention to detail. Treatment quality receives near-universal acclaim. Guests highlight expert therapists, luxurious product lines, and signature experiences like the anti-pollution facial series. The heated pool, fitness center, and relaxation areas round out a full-day wellness destination. The spa earned its Forbes Five-Star rating for good reason -- service is polished, personalized, and anticipatory. Some reviewers note that the infinity pool and gym are restricted to hotel guests only (not available to spa-only visitors), which can feel limiting given the premium pricing. Occasional reports of crowding during peak weekend hours and minor service inconsistencies exist, but these are outliers in an otherwise stellar review profile. This is Philadelphia's top-tier luxury spa experience.
