This review is for the Santana Row location. They have other locations in southern CA
It is pricey, but the spa is great and any appointment gives you access to the whole hot tub -steam room - gigantic showers - cold towels/cucumber slices area for the entire day. Great place to just go relax for a few hours. I know some friends who got a package that included some 2 for 1 coupons that not everyone has been able to use up. If you get those, you can share with a friend or relative.
