Pros (+) We recently stayed here during our visit to the Canton Fair. Pluses are location in Guangzhou, close proximity to the metro (400m away), very friendly concierge staff who were always willing to help, and the hotel had daily shuttles to and from the Fair. The hotel western restaurant was also very good in their western cuisine options and food.
Cons (-) The breakfast additional charge was pure extortion. It was 5x cheaper to eat breakfast at the Fair than the hotel. We did exactly that in the end and there were many dining options available in all complex halls, including McDonalds and Papa Johns amongst others.
