It was in the city but underground. It was underground in the city (sounds a bit more natural I think)

The place was pretty dark and has  had nice decor, such as colorful lighting.  - You can use has to describe the place but because you started the sentence in past tense with "was" it's better to keep the rest of the sentence in the same tense.

Also, I liked that place it because it wasn't very big. "Also" doesn't really link what you are saying in this sentence to the previous sentence, so it's not needed. You could however say "Also, it wasn't very big so I liked that". You can replace "that place" with it because we already know what you are referring to from the context given in the rest of the post.

My score was okay. おつかれさまでした :P

It was a nice refresher for me.

I could understand everything you were saying easily, so conversationally it was fine. There's just a few grammatical errors which you will be able to fix yourself the more you use English. Please let me know if you don't understand any of the corrections or need further explanation!
