Ciragan Palace Kempinski Hotel

Set on the Bosphorus, this large, five-star luxury retreat is set in an opulent 19th-century marble Ottoman residence, spilling out into several newer buildings.

The main palace building houses seven suites, popular among visiting royalty, heads of state and Hollywood stars.

The Ciragan Palace provides guests with every conceivable mod con – indoor and outdoor pools, a hammam, fitness centre, gardens, and even the occasional classical concert – alongside mesmerising views of the Asian side of town and the Bosphorus Bridge.

There’s a superb breakfast buffet, too – pricey, but could keep you going until the evening.

Lounging in the hotel’s heated infinity pool, watching ships sail down the Bosphorus strait, is a total luxury. After all, you are staying in a real Sultan’s palace.
