First - the bad points! Very small room, Superior means it has a window, even if the bed is pushed right up to window and curtains trapped between window and bed. Shower does not have a curtain, so the entire bathroom gets wet. However, this is Singapore, not known for the size of the rooms.
The staff are excellent, very friendly and helpful. The rooms and public areas are very clean. The location is also good, being central for most areas. At an extra charge there is a private (I think) cafe/restaurant which is open for breakfast and lunch with some good food options.
I would go again to the Ibis budget when next in Singapore. In spite of my opening comments, it is good value.
