I'd go back anytime to this Conrad. Upgrade to Conrad Suites could be nice, but it is also far from all the action and, if the dedicated pool is still just 1.20m, does not seem so attractive anymore.
Our room in the A section (1117) was huge, and could not notice any flaw regarding cleanliness. As a HH Gold/Diamond, I think this is one of the best hotels in SE Asia to spend your money in, and have a great stay.
