Which is better, 24th floor 10 floor or 2 1 floor?

Suggestions for the selection of 24-storey buildings are as follows:

1, 10- 12 layers: floating layer and sinking layer, preferably not selected.

2. 13- 14 floor: Generally, the machine for the second water pressure increase is easy to be located in the middle floor, and the house with 18 floor may be located in the 9- 14 floor. Before buying, you should ask clearly. Most salesmen are not very clear about which floor this is. People with shallow business may not know it at all, so it is best to look at these two pictures on the spot. 3. 15- 18 floor: this is the best floor, with a good view, and it is lucky to cross the floating floor. 4.19-24th floor: 2 1 floor can be considered, because the elevator machines are all placed on the roof, and the noise of the elevator on the top floor is too loud to be heard during the day and obvious at night, so the 24th floor is not considered. If the elevator is a good brand, floor 2 1 is also a good choice.
