Burj Khalifa is not a hotel, but it houses the Armani Hotel Dubai that consists of 160 rooms. As its name indicates, this exceptional luxury hotel was created by Italian fashion designer Georgio Armani. The highest floor you can sleep at is floor 39, in one of the Armani Signature Suites.
The cost of spending the night at the five-star Armani Hotel Dubai in Burj Khalifa starts between $680 and $1145 (from 2.500 AED to 4.200 AED) per night, depending on the date you wish to stay at the property.
