I like the place___I stayed at in Hongkong. A.where B.in which C.that

I like the place___I stayed at in Hongkong. A.where B.in which C.that

选that,定语从句，限定place范围，不选in which,因为有at 了，不选where，因为定语从句绝不会用where

C.
一、先行词是the polace (表示地点的)。
二、the place在从句中做stay at的宾语。 试比较：
I like the place where I stayed in Hongkong .
I like the place at which I stayed in Hongkong .
I like the place that I stayed at in Hongkong .

which
that
which is better

where
条件状语从句 where指代之前所呆的地方追问不是定语从句吗
