Spa Equilibrium is a first class spa. Offers an extensive list of services, facilities are posh and well-maintained. I enjoy the wet and dry saunas. The personnel are professional. The atmosphere is very relaxing and quiet. I was impressed by the women's area. They offer every toiletrie one could need for a shower, washing one's face, plus have fruit and light beverages available. The massages I have had there have been a delight. They are done according to my preference, so work through the knots to my satisfaction. Gift certificates are available, which make the best gifts. This spa is located in oldtown SF.
