I ran a training programme for an international group in January at this hotel and it was great. Right next to the Rocks, 5 minute walk from Circular Quay, it couldn't be better placed. The actual hotel rooms are spacious and tasteful and the beds are so comfortable. Try to get a view overlooking the bridge and Opera House and if on the other side, go higher up to avoid the road noise.
The conference staff were second to none especially Ajay and Calvin, thank you. The breakfast buffet is great (again great staff thanks especially to Silvano) and the food from the cafe on the ground floor really nice.
The only other thing that let's this hotel is the speed of service from the reception. Whether there in person or calling by phone, they seem to take an inordinate amount of time to serve each customer, such a shame as if it wasn't for this I would give this wonderful hotel 5 stars. Needless to say, I hope to be back.
