Just finished a stay there. The renovation on the rooms are quite well done IMO.
The major improvements are :
1) New interior decorations and completely redesigned color scheme
2) New furniture and fittings throughout the room and improved minibar
3) Upgraded A/V system with new large LED TVs and Bose sound system
4) A cool new in-wall amenity box
The rooms certainly feels much more spacious especially the L600 rooms which in the pass, does feels a bit "cramped". The L900 keeps the layout largely intact but with a new refreshed look. The bathroom has been left largely untouched post-renovation except for an upgraded in-mirror TV but the hotel rooms all have first class bathroom to start with. Wish they have installed the skyshower though.
