Choose between views of the Mediterranean Sea or the mountains at the 483-room Ritz-Carlton Hotel Arts (from $449), a beachfront skyscraper encased in glass and steel. Book a club-level suite (floors 30 to 33; from $736) for access to the private lounge and personalized concierge service. At night, dine at Adrià disciple Sergi Arola’s eponymous restaurant on the second floor, featuring reinvented tapas like patatas bravas served in a row of aioli-topped cylinders ($14).
Spot architectural masterpieces like Casa Milà and Sagrada Família from the rooftop terrace of Hotel Omm (from $294), where moodily lit hallways and piped-in beats contrast with the 91 airy rooms accented with blond wood. Downstairs, Michelin-starred Moo brightens its dishes with herbs and edible flowers from the patio garden, while the busy lobby bar attracts locals tucking into dirty martinis made with Spanish olives ($17).
Indulge in a midday siesta in your in-room hammock at Casa Camper (from $236), a converted nineteenth-century Gothic building boasting modern design accents like exposed shelving and Tivoli radios, plus the slick Asian-fusion bar Dos Palillos on the ground floor.
