If you are thinking about it, do it! This place is simply fantastic!
We so enjoyed the spa retreat, with all of it's thoughtful touches. You won't want to leave and explore Seattle, it is so relaxing. It is indeed a private spa, just for you. Down to the robes, slippers, aromatherapy diffuser, and Alexa to play whatever music soothes your ears.
Comfy beds to sleep like a baby in after a good soak and a proper sweat in the sauna.
Thanks for sharing you wonderful place, Jeff!
