Regarded as the Calvin Klein of Spain, Antonio Miro creates a streamlined, if not entirely plain style inside the Miro. The rooms follow a white with slate carpet theme and just up their size, rather than their amentities  as they rise through the luxury ranks. But it's the touches of red, citrus and artworks that give away a certain flamboyance that plants it in Spain. What the Miro has going for it is position. Sitting on the doorstep of the Guggenheim, it's an easy in and out to the main gig in town. There's a spa and gym to unwind in, while Bar Miro brings live jazz to the hotel each month.
