hello. how far is bar street from hunshi donglu, ocean hotel in Guangzhou

As I know, there are three famous bar streets in GZ, namely Yanjiang Road, Huanshi Road and Bai'e Road. So which one do you refer to?

If you mean the one at Yanjiang Road, you can use the subway line 5 to the Railway Station and then change to line 3 to Haizhu Plaza Station. Get out of the station, you can walk along the Yanjiang Road to get to bars.
if you mean the one at Huanshi Road, from your hotel, you can walk along East Huanshi Road to Taojin Road. Then you can walk along Taojin Road to find that bar street,
