In Barcelona, design hotels come with a backstory. On Passeig de Gràcia, Claris pairs its art collection with a pre-Columbian museum and a Mayan-inspired spa. El Palauet keeps an ornate modernist façade and listed ceilings for a handful of suites, while the Grand Hyatt, up in Sarrià - Sant Gervasi, favours Art Deco lines and a panoramic restaurant.
