Which is better, stacked on the villa or stacked on the villa?

I will consider personal needs, preferences, life scenes, budget and other factors when choosing the villa.

Folding is quiet and has private space. But you need to climb stairs, which is unfriendly to the elderly. And space is limited.

It is convenient to fold down, spacious and has a garden or terrace. But the price of the lower stack will be higher than that of the upper stack.
