Hotel and resort operator Four Seasons has opened its newest property in Baltimore, US.

The 256-bedroom Four Seasons Baltimore boasts a 10,00sq ft (950sq m) spa with eleven treatment rooms including several suites with private soaking tubs - and separate men's and women's relaxation areas, sauna and steamrooms.

Featuring products and treatments by ESPA, the spa also has a large relaxation zone with two pools - including a year-round heated pool with an infinity edge that spills into the harbour.

Spa Director Shanna Silverman said: "Among our eleven treatment rooms are two suites with floor to ceiling harbor views and their own soaking tubs, and the couples suite is both a romantic retreat, or the perfect setting for a bridal party to pamper before the big day."

Four Seasons has invested US$200m (150m euro, £127m) in the hotel, which was designed by Beatty, Harvey & Coco architects of New York in partnership with California-based Hill Glazier Architects. The Hotel's interior design is by Brayton & Hughes Design Studio.
