Whenever I go to a spa, I always check the certifications on the wall. If there are none, I just ask for the prices and then go and you will never hear from me again. If there is and I know that the certificates come from an Accredited Massage School, well, I will be your customer for ever and I will endorse the spa as often as I can. The last spa that I went through, I have already endorsed and told everybody that I know who are into these things. Because based from my first hand experience, they were really good and it is not just me who says this but also my husband. Although if you consider the price, slightly higher than others but definitely worth it.
