There are several different areas on and around Huang Shan to spend the night. Aside from the more luxurious and expensive hotels tucked away in the mountains themselves, the most comfortable are in Tangkou, a town that serves as the point of departure for most tours. Tangkou is also well outfitted with restaurants, shops and grocery stores selling climbing and hiking gear. The Huangshan Xiangang Hotel offers inexpensive, clean rooms; the Tangkou Hotel is the top luxury hotel at around RMB 600 per night.
The Hot Springs Area (Wenquan), situated a bit further into the mountain range, offers more accommodations in a more picturesque and calmer setting, though with a slightly rougher edge. Taoyuan Binguan, Wenquan Dajiudian and Huangshan Binguan all offer decent rooms(if generally rather small and often rather damp) . You can also take advantage of the hot springs themselves.
Huang Shan's popular peaks feature some fine places to stay, many with spectacular views just outside your window. The "summit area," located in the north between Purple Cloud Peak, Pine Forest Peak and the Beihai (Sea of Clouds) is home to a handful of hotels, including the Beihai Hotel, ideal for getting a jump on the legendary sunrise over the Sea of Clouds, and the Xihai Hotel, a Swiss-style comfort zone. Cheaper dorm-style accommodations can be found at the Paiyunlou and Shilin hotels. Be prepared for the mountains' persisitent dampness if you're staying in cheaper lodgings.
