I have stayed at this hotel on two occasions. Both times I was completely satisfied. Unlike many modern hotels the rooms are large and have high ceilings giving a very spacious feeling. The restaurants are good but you do have to make reservations for them since they are perpetually full.
The one complaint I would have is the selection of pay per view movies is tragic at best.
I also wanted to mention that I read the reviews of the hotel and found the ones complaining of bad service to be perplexing. I can report absolutely no issues. Everything worked like clockwork, all staff behaved in a very professional manner.
I would and will go back to this hotel every time I visit Singapore. It is simply better than the rest.
