If the 23rd floor is the top floor, the 22nd floor is the best.
Because for high-rise buildings, the higher the floor, the better the living comfort (except the top floor), the more abundant indoor lighting, the wider the field of vision and the fresher the air. However, if it is the top floor, although it has the advantages of the previous aspects, it has two fatal shortcomings, that is, the roof leaks easily after the sun is exposed in summer, and the indoor heat is unbearable.
