+1 for the older property (IC @
bugis).
I agree on all points
Viennaflyer mentioned above, would add:
IC Singapore: Rooms recently refurbished, nice views from rooms in main tower. Pool area is spacious and offers views. Club is very good but can get crowded as well and has no daylight, i.e. feels a bit dark during the day.
IC Robertson: Rooms do not have a proper workdesk. Pool area small and no views (blocked by wall next to the pool). Club is more modern and airy plus offers an outside area.
