The spa has a lovely decor, the lounge is a nice place to hang out before or after your treatment. I had an 80 minute signature massage and enjoyed it very much. My massage therapist was attentive, thoughtful, and communicative.
I have been to Burke Williams and they have a lovely facility but it is often overrun by young ladies out to party at Santana Row. If you want a relaxing lounge area don't do there. The Spa - Los Gatos is a better choice.
Great experience overall.
