In a glorious setting overlooking the Bosphorus, the Four Seasons in 2008 opened this 166-room luxurious hotel in a former 18th century palace. Expect the usual Four Seasons amenities including a huge fitness center, a 90 foot outdoor heated pool, an indoor pool and lavish spa. As ever, the Four Seasons is particularly welcoming to children with special treats as well as cribs, rollaway beds and babysitting services.
