Visit the Tallest Building in the World

Dubai always venture at being the best at everything. In 2009, the Burj Khalifa took its place as the world’s tallest building at 2,722 feet which houses hotels, apartments, bars and restaurants. I know what you’re thinking, that’s a hell of a lot of windows to clean! In fact it takes 36 workers three to four months to clean almost 2,500 windows.
