How about nigro Hotel in Changsha? How many stars? Provide information?

I have always heard that the scenery of nigro Hotel is invincible, so I came to Changsha to punch in. The hotel is located on IFC 86-92, which is a real cloud hotel. The design of the guest room is full of sense, which conforms to the aesthetics of young people. You can go to the bar on the 93rd floor for a drink in the evening. The band is great. Moreover, if you book in official website four days in advance, you can enjoy a 20% discount and a free breakfast for two, and members of Discovery Tour can also enjoy an additional 10% discount (up to 70%).
