Hi, I went and asked. According to reception, there isn't one, though confusingly there is a sign saying "Beauty Farm". There is massage, up to 40 euros half an hour. The receptionist said that one has to go either to the Iberostar Albufera Park, which is a fair way (by foot anyway) or to the Esperanza Hotel, which is close by. They have a number of "packages", e.g. from 65 euros for a "hydra flash spa" to 162 for a "deluxe beauty for women". And there are a variety of single treatments.
