Pros: this hotel achieves to have all the Westin amenities, standards and things that make me choose a Westin: 24 hrs. gym, excellent toiletries, flavored water in the lobby, affordable luxury, and a decent service. The free breakfast is good enough for a short stay (easily to get tired). If you are visiting any Expo nearby this place rocks.
Cons: I'm a bit disappointed with some aspects of the service, during check out they wanted to charge me thus if mini-bar that didn't take, also at evening the cleaning staff is loudy outside the rooms. The wifi is terrible, no matter if its free but should work properly. Please be aware that you will be next to the Expos but far far away from Guangzhou.
In sum, I'll stay again here, they only need to fix minor issues.
