personal experience is that:
Y5 room do not have option for mountain view. wifi is good enough for me to handle work emails, but i feel my maxis network better. tower 3 is furthest away from anywhere u wanna go.
superior deluxe room best suited for me. located at tower 2. bigger than Y5, and can choose mountain view. i only clock about 80-120 points per year but can get that for free already.
For superior deluxe - higher floor ones (yet to be renovated) are still with carpet...those renovated ones @ lower floors are now without carpet - might be more noisy if some inconsiderate neighbours above u drag chairs or stomp on the floor..
