Part of the boutique Doyle Collection, this is a thoroughly modern property. The rooftop terrace is a real gem, with outdoor fireplaces, flat-screen TVs, cushioned sofas and rugs. An excellent place for a workout, the hotel’s Third Space gym and spa has an 18m indoor pool, as well as alternative therapy treatments. 250 bedrooms have accented vibrant colours and bold patterns, augmented by contemporary art pieces. Families are welcome with open arms; The Marylebone provides kids’ menus, free meals for under fives and teepee beds with inflatable mattresses, camping lamps, cookies and a flask of milk on request.
