You will hardly find a better price for a 5 star hotel, we stayed there 5 nights and the only 2 things I would complain is the heating and the location.
The location is not too far from downtown Guangzhou but there is just nothing close by except old buildings, roads and highways, so we always had to take a cab everyday nevertheless you do not need to worry because they have a good sound proof windows so it is quiet inside.
The heating was partially working inside the 2 rooms that I have been, it was not cold inside but it did not allow me to go up to the temperature I wanted.
Other than that everything was great, the service, the breakfast and its variety, the cleanliness of the rooms and hotel, the spa, the pool, the amazing massage etc..
Overall, if you are looking for a very quiet place and if you don't mind to be a little outside the action and don't mind what surrounds you, this is definitely the place to go
