We stayed two nights in that hotel after having spent an extraordinary stay at the Crown Plaza in Sanya so our judgement might be a little biased.
The rooms smelt, I don't know what, but it did. Typical Chinese atmosphere, in the worst meaning. You'll be welcome in your room with a set of everything you need to enjoy a one night stand company (I was there with my family!), and don't be surprised to share the elevator with some young girls making up their faces to go God knows where...
Just a reminder, it's a 5 star hotel. more
