Concierge.com's insider take:
Set between the Guggenheim and the Museo de Bellas Artes, this 50-room boutique hotel is both superstylish and a great value. The room interiors, conceived by Barcelona fashion designer Antonio Miró, are all mod white-on-white, with beige leather sofas, velvet curtains, recessed lighting, flat-screen TVs, and sliding wall panels that conceal hidden office nooks, entertainment centers, and wet bars. The property includes a convivial pintxos bar and separate hot tubs and saunas for men and women. The hotel's best asset, though, is its welcoming, friendly staff; they'll assist you with everything from directions to dinner reservations to finding a doctor who makes house calls.
