Another Kempinski hotel to make the cut for its awesome autos is Instanbul's Ciragan Palace. Located on the European shores of the Bosphorus (the strait that forms the boundary between Europe and Asia), the palatial hotel is every bit as opulent as it was during the glory days of the Ottoman Empire. Your choice of a Mercedes Maybach 62 or a BMW 7 Series will chauffeur you around town, while those staying in the Palace Suites will be greeted at the helipad by their private butler.
