West Lake visit

Almost of all the hotels near the lake are expensive, so I suggest you to find a express hotel such as Hanting Hotel, which has a reasonable price.
From the local airport, you can the shuttle bus to reach the city center and take a taxi to reach your hotel. Taxi fare in the city is not very high, so do not worry about.
It is the coldest time of the city, the average temperature is around 1C, sometimes, it will snow according to the previous records. If you want to come at that time, I think you need to take thick coats and sweaters.
