What is the best way to take a transport from Guangzhou Baiyun Airport to BangTai International Apartment?

The issue is not during usual bus operating hours. It is arriving at the Baiyun Airport at 1:20 am way past midnight.

The address of the hotel is No43, Xingangdong, Tienhe District
Pazhou Exhibition Center Area.
Guangzhou.

Assuming that it is still possible to hail a taxi, what would the taxi fare estimated to be?

Please advice.

Thanks and regards,

Gordon
