There are 17 elevator rooms in total, and the 16th floor is a better location. The high floor allows you to view the mountains and water, and the vision is bright. It has 17 layers of protection that can insulate from heat and cold, and also prevent the possibility of rain and water leakage. The air is relatively fresh (11-13 is said to be the layer of ash and smoke pollution). It is even more uneconomical to choose a low-rise room (below 7 floors), which is a waste of shared expenses.
I went to the lower floor instead of the middle floor. I prefer the high floor. The 16th floor is pretty good.
