Ayasofya Hürrem Sultan Hamam
There are several magnificent steamy Ottoman bathhouses to choose from in the city, including the Çemberlitaş, Cağaloğlu, Galatasaray and Sülemaniye baths, but in 2011 for the first time it's also possible for visitors to try out the spectacular 16th-century Ayasofya Hürrem Sultan Hamam right in Sultanahmet Square and designed for Suleiman the Magnificent's scheming wife Roxelana. Think acres of marble, the sound of running water echoing around stupendous domes, and a massage fit for a sultan. You'll come out almost purring.
