Rooms and suites

Rooms combine classic New England styling with Asian touches and come with marble bathrooms, walk-in wardrobes, Nespresso machines and Diptyque bath products. Suites add separate living and dining areas, some with kitchenettes, and the largest is a 2,600-square-foot Presidential Suite. For families, suites can be joined to adjoining double or king rooms, and children get MiniMo bathrobes, coloring books and a play tent.

The Spa

The spa has separate men's and women's heat and water areas, each with a quartz crystal steam room, vitality pool, experience showers and an ice fountain, plus a relaxation lounge and a couple's suite. The hotel asks guests to arrive 30 to 45 minutes before a treatment, because the thermal facilities are open only before treatments. Non-guests can book, but spa and fitness center access is limited to adults 18 and over. There is no swimming pool.

Fitness

The fitness center is reserved for hotel guests and residents, with personal training and group classes available.

Restaurant, bar and spa

Ramsay's Kitchen is Gordon Ramsay's first restaurant in Boston, a casually refined dining room that serves his Beef Wellington alongside dishes from around the world and twists on local favorites, with a bar and lounge and a wine list. Breakfast is served daily from 6:30 to 10:30 a.m., lunch runs from 11:30 a.m. to 3 p.m. Monday to Friday, with brunch at the same hours on weekends, and dinner follows from 3 p.m. There is no dress code beyond no swimwear. The same kitchen supplies in-room dining.

The Spa at Mandarin Oriental, Boston is open to outside guests as well as hotel guests, for massages, facials, body treatments and mindfulness sessions. Cancellations need 48 hours' notice to avoid a 100 percent charge.
