The Fitness Center at Four Seasons Hotel San Francisco

"Its pool and fitness center are outsourced, and its business-centric SoMa location lacks the prestige of Nob Hill, where some if its strongest competitors reside"

"Take a dip with city views in the pool, or join a class at the 127,000 square foot fitness center before getting spoiled rotten at the spa, which offers stress-busting treatments from aromatherapy to detoxification"

"There’s an enormous onsite health club with a pool and vast gym that’s free to hotel guests"

"(the best hotel gym in the city, with a full-size pool), a 2-block walk to Union Square, and a vibe that combines sophistication with a hipness far more refined than the W or the Clift"

"The Cal-Med restaurant, Seasons, offers a sophisticated spin on surf and turf, and the vast Sports Club/LA, the city's top health club, has a gym, fitness classes, a pool, a full spa, a basketball court, and even Gyrotonic and Budokon studios"

"The full range of services and amenities includes tech assistance and one of the city's best gyms, boasting a regulation-size basketball court and lap pool"

"There are also the Yerba Buena gardens nearby and a stunning lap pool inside the hotel for when you need a break from sightseeing (there’s also a full-on Equinox gym)"

"Covering three levels, the fabulous sports club and spa—now run by Equinox—is free to guests and offers an expansive state-of-the-art fitness center with classes and trainers, a six-lane lap pool, whirlpool, sauna, steam and separate men's and women's locker rooms"

"• The luxury hotel doesn’t have its own onsite gym, but you gain entry to the next-door Equinox Sports Club, a big perk considering the complex’s size and range of offerings"
