Basileus Hotel is a newly-opened boutique hotel in the Sultanahmet section of the Old City of Constantinople, which was renamed Istanbul in 1923 when the Ottoman Empire came to an end with the establishment of the modern state of Turkey. As the capital of three successive empires, Roman, Byzantine and Ottoman, Istanbul has long occupied a central role in the histories and cultures of the Greeks, Romans, Byzantines and Ottomans, in succession and is today one of the largest, most vibrant and undeniably cosmopolitan cities in the world.
