Hürrem Sultan Hamamı
Hürrem Sultan Hamamı sits right on Hagia Sophia Square, so visitors already touring Sultanahmet can walk in without planning a separate trip. The website says it has operated since 1556, and it takes online bookings, which helps travellers arranging a visit ahead of time. Four packages are priced in euros, alongside aromatherapy, anti-stress, back and foot massages.
