1. Four Seasons Sultanahmet -- Istanbul, Turkey
Ranking: Lock me up and throw away the key
Lined with lemon trees, the bright yellow building offers incredible views of both Istanbul's Hagia Sophia basilica and the ocean. Rooms are decked out with antiques, marble floors, and damask fabrics, but little remains of the former jail, which was the first modern prison in the Ottoman Empire’s capital.
Coolest remaining prison feature: Literally none. This hotel is all class and no crime. Ok, so the heavy wooden doors to the lobby and the watch towers remain, as well as an inmate’s inscription on a marble pillar, but otherwise this place looks nothing like a prison.
