How do I get to Doubletree Hilton Hotel by bus from Guangzhou Baiyun International Airport?

Is your hotel located at no.391, Dongfeng Road, Yuexiu District? If it’s right, you can refer to the following route.
You can take metro line 3 at the South Airport Station to Jiahewanggang Station. Then you may transfer metro line 2 to Sun Yat-sen Memorial Hall Station, Exit D2. Upon arrival, you need walk southwards for about 11 yards (10 meters), and then walk eastwards for about 930 yards (850 meters) along Middle Dongfeng Road where you can see your hotel.
