This stunning Modernista building was designed by Lluís Domènech i Montaner for the Fuster family in 1908, and it was reported at the time to be the most expensive home constructed in the city. Modernisme's heyday lives again in this deluxe hotel decked out in a palette of magenta, mauve, and taupe. Private balconies in many rooms open onto leafy Passeig de Gràcia. The hotel's Viennese cafe has become one of Barcelona's best jazz clubs, but soundproofing is so good that you won't hear a single saxophone honk in your room. The location is less convenient than most for exploring the city, but if you have your heart set on sleeping in a full-blown Modernista landmark, Casa Fuster is your place.
