More of an urban resort and convention center than a mere hotel, with glass elevators gliding smoothly up and down a 15-story central atrium, the Rey Juan Carlos is a surprisingly affordable American-style ziggurat. The lush garden adjacent to the main building has an Olympic-size swimming pool, a pond with swans, and a superb spa. The elegant rooms have gorgeous wood doors, brass fixtures, and bathrooms appointed in marble, with spectacular walk-in showers. What's more,
the Royal Polo Club of Barcelona is just a few minutes' walk away.
