The One Barcelona

Designed by interiorist Jaime Beriestain, this five-star stunner has 89 light-filled, gold-and-cream rooms (corner suites like 203 are lovely). Works by Catalan artists, including Miró and Tàpies, adorn public spaces; rooms feature pieces by Chilean artist Fernando Prats. A panoramic roof terrace, bar-restaurant and plunge pool, a spa (indoor pool, sauna) and a 24-hour gym are among the facilities.
