This nineteenth-century Ottoman mansion that features hand-painted ceilings and marble inlays in its 166 plush rooms opened in June 2008 and is a dream destination for those seeking a romantic interlude. The views of the Bosphorus Strait, which flow through the heart of Istanbul, are worth the trip alone. Fine restaurants and pools overlook the Asian shore and you can choose a room overlooking the city, the waterfront or the lush gardens. The 22,605-square-foot spa is inspired by the Turkish bath (hammam) and even includes a private spa suite for two. Following your relaxing pampering, head to the hotel's main restaurant, Aqua, which takes its inspiration from the Bosphorus, accenting dishes from Mediterranean, coastal territories with rich, local elements.
