Head to the Hurrem Sultan Hamami in the heart of European Istanbul for a tradition Turkish spa treatment. Standing where the ancient public baths of Zeuxippus used to be, the current bathhouse was built in the 16th century on the orders of the Empire’s most powerful woman, Hurrem Sultan. You can choose from a variety of traditional baths and massages to suit your needs, including traditional Hammam rituals and aromatherapy. When you’re feeling completely relaxed and done admiring the bathhouse’s stunning Ottoman architecture, head to the on-site restaurant, which serves a delicious selection of traditional Turkish dishes. – Tripadvisor
