Luxury and panoramic views from the 43rd floor are the big selling points at the Hotel Arts spa, where they also offer beauty treatments using Natura Bissé cosmetics. The facilities, located in a duplex on floors 42 and 43, boast exquisite design and an impressive vantage point of the sea. They have it all: hydro massage, sauna and steam baths (sex-segregated), elegant relaxation areas, eight spa treatment booths (two with sea views) and two terraces on opposite sides of the building, so as not to miss a minute of sunshine. How can you get in on it? You can use the water circuit (for about three hours) without any additional treatment for €45. And if you decide to get a treatment, you can get, for example, a 30-minute neck-and-shoulders massage, or a 30-minute legs-and-feet massage for €90 each.
