How do you use "which" as a relative pronoun? How do you use "which" as a preposition relative pronoun in chinese?

For example, I'm trying to translate：
 There is a cozy tea sitting area in our shop which is in front of the Campbell's farmers market on every Sunday

美週末星期天，在於商店裡，有一場舒適（座位／休息區）；我們的店位於農貿Campbell市場前。

My translation uses two complete sentences, but I want to make it a sentence followed by the preposition relative pronoun "which is in front of the Campbell's farmers market on every Sunday".
I am a native Chinese and Linguistic major graduate student, I guess my answer is suitable:

每周末我们位于Campbell农贸市场前面的商店里都会提供一个舒适的茶座。

Or:
每个周末,我们位于Campbell农贸市场前面的商店都会提供一个舒适的茶座。

Either is Ok and I prefer the later one.
