I spent several months in San Juan del Sur in 2010, and frequented Spa del Sur at least 6-7 times during that period. It is a beautiful, clean open space that is run by a wonderful couple from North America, with everything up to North American spa standards. I had several massages at Spa del Sur, mostly with Kai, who is absolutely fantastic and incorporates many different massage techniques into one relaxing and tension easing session. The prices are very reasonable (and cheap compared to Spa/massage prices in North America!). This spa offers much more than massages, but I would highly recommend a massage by Kai to anyone visiting San Juan del Sur - one of the best treasures found in this little town!
