My stay was terrible. I asked for a quite room and they assured me by email and when I checked in that I would be given a quite room. First thing in the morning until evening non stop load noise of works going on above room. Asked to speak to manager and did not appear until I was checking out and turned up when I said I was not going to pay until I could speak to the manager.
Singapore people are honest, but manager in this hotel in a lier and crook.
I also emailed Accor hotels about this. They did not even reply after two months of waiting. Disgraceful.
