If you are not Chinese citizen or long-term resident, you don't get to enjoy much. Self-checkin is only for guests with a Cinese ID card, so foreigners need to br checkedbin manually, and they do not even have a piece of paper to give you for the room # or wifi pass. If you are a foreigner, again, you don't get to use Alipay, so you cannot use vending mac/ine, you cannot order roomservice etc. I don't speak Chinese, and the smart speaker in the room only understand Cinese.
Face recognition key was convenient, but nothing notable. Nowadays, the China government is restricting foreigners w/o Cinese bank account to use mobile paymebt apps, so this place is not for visitors. Self check in was more efficient at CitizenM than here. Without Alipay, again, you don't get to enjoy the nearby shopping mall either.
Besides those, breakfast was very very good.
