When it comes to hotels, a room with a view is desirable, but a pool with a view is something special, especially when that view is 24 stories straight down.
Part of the hotel's 30-meter indoor pool hangs out past the building's edge, and is constructed with a glass bottom, giving swimmers the sensation of swimming in the sky.
A spokesperson for the InterContinental Hotels Group, parent company of Holiday Inn, told CNN:
"We wanted to provide our guests a unique swimming experience, and let them feel they're vacationing even in a bustling city."
