Four Seasons Hotel Abu Dhabi at Al Maryah Island

What the classifiers highlight

Al Maryah Island puts this glass tower between the business district and the Louvre, minutes from Saadiyat's beaches. Forbes gave it a Five-Star rating and highlights the 2,000-piece art collection, seven lobby columns representing the emirates, and a 21,500-square-foot spa, the city's first to earn Forbes' top mark.
