If i want to go to Mt. Huashan and stay for some days, where can i stay and what is the prices?

I think two days are enough for visiting the moutain. If you want to stay there for some days, I think you can live in Huayin City, at the bottom of the mountain.
In Huayin City, Aster Hotel is suggested, which is located on the Middle Section of Huayue Road. The price is about 300 RMB per night for standard room.
In the mountain scenic spot, Xifeng Hotel (West Peak Hotel) and Dongfeng Hotel (East Peak Hotel) are suggested, but the prices will be high.
