I'll arrive to Zhangjiajie train station on Sep. 26 and I'd like to know how to i reach this hotel.

Jinjiang Inn Hunan
No. 51 Ziwu Rd.
427000
CN
+867448398888

And by the way, do I need to call them in advance to let them know when I'm arriving or can I just show up and give them my reservation number?
Also, I paid for the stay already, so I hope they won't try and charge me anything right?
