Old and new Madrid come together at URSO, which you'll find between the Chamberí and Chueca neighbourhoods, and within walking distance of the Royal Palace and the city's 'Art Triangle'. The 78 rooms are done up in cosy, subdued colours that lend themselves to relaxation. If you still crave more of the stuff, though, head to the spa and opt for the two-hour face and body treatment designed exclusively for URSO by Natura Bissé. Be sure to have your home-made breakfast in The Conservatory, where you're surrounded by a vertical garden topped by a skylight to get you in the mood for the day ahead.
