J Hotel in Shanghai has officially opened and now holds the title of the world's tallest hotel at 628m.
Owned by Jin Jiang International Hotels, the world's second-largest hotel group,it's the first of a series of ultra-luxurious hotels being opened by the company.
The interior was designed by a novelist and screenwriter, which led to a very different look with abstract meeting conservative throughout the hotel.
J Hotel Shanghai Tower has 165 rooms, including 34 suites. The staterooms and suites are located from floors 86 to 98 and vary from 62 square metres to 380 square metres.
Each room can be controlled by a smartphone, with built-in sensors allowing control of the TV, curtains, air conditioning and lights - as well as the butler - all with a simple tap.
However, it's achieving the title of world's tallest hotel is likely to come into question as other hotels may claim the building isn't just a hotel, but also includes dozens of apartments.
It will, for the time being, at least be known as the world's tallest "twisted building", however.
And, while it is the second tallest building in the world, it doesn't come close to the number one - the Burj Khalifa - which is nearly 200m higher than the Shanghai Tower, reaching a whopping 828m.
But the Shanghai Tower is still nearly twice the height of Auckland's 328m Sky Tower.
