Treatments and massages

At Martin'Spa, you can let yourself be pampered with non-therapeutic wellness and beauty treatments. By “massage” we understand a body care treatment that is conducted according to specific techniques. Our masseurs and beauty specialists are trained in these treatments in certified centres. These treatments are not of a medical or paramedical nature. 

Entry conditions
