This grand, marble and mosaic warren of 42 treatment rooms, eight hydrotherapy rooms, steam rooms, swimming pools, saunas, snow rooms, floating baths, thalassotherapy pools and Turkish hammams, is pure palatial indulgence. Males and females are kept separate, however if you wish to mix there is a small couples spa on a separate floor where you can enjoy joint treatments and use of the facilities including sauna, steam and couples hammam. The spa menu incorporates ancient, traditional practices, with classic treatments, Asian influences and new-age holistics, as well as luxurious facials, scrubs, wraps and Ottoman rituals.
