Definitely recommend this spa. Had a great hot rock massage here this week. The facilities themselves are amazing. Massive locker room, and phenomenal post-treatment area with steam rooms, saunas, hot tubs, shower walls, private bathtubs, you name it. Plan to hang for a while. Very relaxing - you don't want to leave! Great iced teas, hot teas, cucumber water, all my favorites. Big fan of this spa for sure.
And just a note, weirded out by some Yelpers comment that this spa was small. My friend and I were commenting multiple times on how huge it was. Maybe if you're not used to small SF city spas you'd find it small but I certainly didn't! :-)
