I have also been researching Spanish style spas on my travels to Spain recently.I found this spa in Nerja and checked in for half a day.Apart from making me wear a plastic hat and some awful plastic slippers it was great.It was a mixed spa and a place where people were going for a good chat and some treatment in the hydrotherapy pools.I had to take my place in the hydrotherapy pool and move from station to station where the water worked on different parts of your body starting with the feet, calfs,thighs etc.You were left to enjoy on your own and then called for a massage.It was Carnaval so there were few clients and I had a very good massage.If you are in Nerja please visit this Spa called Spa Paraiso del Agua in Nerja town Andalusia, Spain.
Enjoy
