I want to go snowboarding and see Harbin Ice Festival.

For convenience, I would suggest you stay near the Central Avenue. There are many hotels ranging from the small inns to the star hotels in the street. From here, you can visit the Central Street, St. Sofia Orthodox Church, Grand World of Snow, Zhaolin Park, Dragon Tower and other attractions. If needed, you may also find a local travel agency to book a guided trip in advance.
