Sanctuary Spa will allows have my heart, seriously, they have a one-of-a-kind location. The Spa is setup to frame the Praying Monk on Camelback when you check-in, there is a man-made stream/water-feature that the spa surrounds, the mens locker room has a huge lounge area (women- not so lucky).
I was employed here a few years ago and have visited for massages. Request Gary or Anita and you will not go wrong! Many of the Massage and each of the Facial Rooms look into the courtyard with the water-feature. There are often hummingbirds that play here! When it rains, the roof is metal and it sounds awesome. There is a couples suite, with a fireplace!
When visiting the spa, make sure to slow down, enjoy the resort and scenery!
