Four Seasons Hotel Istanbul at the Bosphorus

What the classifiers highlight

Housed in a 19th-century Ottoman mansion steps from the Besiktas ferry quay, the hotel rotates contemporary work by Turkish artists through its public rooms. Forbes highlights chef Görkem Özkan's Aqua restaurant, its fisherman's pot for two served on a terrace above the strait, a waterfront pool, a hammam spa, and a winter ice rink that turns into a summer grill-bar.
