★ Please answer if you have stayed at a 7-day, thank you! I have not stayed at a 7 Days hotel. May I ask what is the difference between an economy room and an autonomous king room?

The main difference between the two is that the economic room is generally the basement, the lighting is not very good, and the interior area is relatively small, the main point is that relative to other rooms is more affordable, but the number of economic room is limited, is not very good to book, generally have to book in advance; autonomous king room on a queen-size bed, the lighting is relatively good, and the interior area is larger! The price is more expensive, the other not much difference, I hope to help you!
