2. Mardan Palace Hotel, Turkey
Built by Russian Billionaire Telman Ismailov in 2009 to the tune of $1.65 billion, the Mardan Palace Hotel in Antalya, Turkey boasts the largest swimming pool in the Mediterranean (fits 1,000 guests) and is touted as one of the most elite luxury hotels in Europe. Beyond the sinfully sumptuous suites and jaw-dropping interiors of gold leaf, crystal, and Italian marble, there are also ten dining spots, 17 bars, a lavish spa and a sunken aquarium full of exotic fish. 9,000 tons of white sand was flown in from Egypt for the beach alone. 24/7 personal butler service is also included.
