We have just spent our first night here and the comments in this thread are spot on.
Am a platinum and the upgrade was ok ('club' room) but not a suite and on a lower floor. Bed is comfortable. We like the decor but the metal chair is definitely an acquired taste.
Wi-Fi is dreadful.
Breakfast in the restaurant is superb. My partner and I have been travelling across Asia using mainly Marriott and Starwood properties, we both agree this has the best breakfast so far.
