Conrad Istanbul Bosphorus

The S-shaped tower was designed specifically so that nearly every room catches a slice of the Bosphorus, and on a clear day that deep blue strait does most of the decorating. This upscale Beşiktaş hotel has a lobby hung with works by celebrated Turkish artists, clay tennis courts, indoor and outdoor pools, and a spa built around a traditional hammam. Foreign dignitaries and Istanbul locals both seem to find their way here.
