please recommend good hotel near train Station from Beijing and Guangzhou airport not expensive

Hey, if I understand correctly, here is what you wanna know:
if you take a high-speed train to travel from Beijing to GZ, you will get to the South Train Station. Nearby, I know a hotel named Dazhou Apartment Hotel, at Dazhou Village, around 400m from the west exit of the train station. It costs CNY100-140 and may meet your demand.

As for hotel near Baiyun Airport, I know a Feixiang Hotel, which is around 3km from the airport and it provides free pick-up service. It costs CNY150-180 I remember.
