The disadvantage of the second floor is poor lighting, and there are more mosquitoes in the field of vision. The advantage is that it is convenient to go up and down the stairs. Generally, the lower floor is suitable for the elderly to live in, but I prefer the middle floor because it has good lighting and good vision.
According to geomantic omen, the worst is underground or semi-underground and the first floor of the building. Dirty land, sewage and dirt are gathered in the lower floor, and there is no problem on the second floor. The feng shui of room type, size and distribution should be seen on the spot to see if it conflicts with the landlord. If the landlord really believes in finding one, I have a friend who looks at Feng Shui and has a good reputation, but there is a charge. I suggest that the landlord should not especially believe in this kind of feng shui, or not.
