Fashion and fabulous facilities come together at the five-star Six Senses Kocataş Mansions, a heritage property overlooking the sailboat-studded Bosphorus Strait. Be wined and dined at the hotel's five restaurants, including an onsite patisserie serving up freshly baked pastries, croissants and Turkish coffee. The wellness spa, located across three levels in a 100-year-old stone house, is your go-to for pampering bliss. Indulge in a traditional Turkish hammam, a dip in the infinity pool overlooking the Bosphorus Strait or a range of deeply relaxing massages. When you're ready to venture outside, wander 10 minutes along the banks of the Bosphorus to Sariyer, Istanbul's northernmost district, home to seafood restaurants and the Sadberk Hanim Museum.
