The Casanova by Rafael Hotels

The hotel prides itself on top-notch service. Housekeepers leave bonbons or flowers on pillows in Superior rooms and suites, and concierges create unique itineraries (a tour of La Boqueria market with a Spanish food expert, for example). Such attention extends to the 124 light-filled rooms and public spaces, which feature works by Catalonian artists—a nod to the nearby Bohemian artists’ enclave, El Raval.
