I stayed one night in the Merlot Room when I was in Margaret River for business. I was both comfortable and warm and the facility was very clean with really pleasant staff. My only issue, which affected my over all rating was the noise. People coming and going as my room was next to the reception desk and the area above my room before the guests settled for the night. And (2) The air-conditioning in the rooms needs updating, it is very noisy.
Everything else met my expectations and the noise would not be a factor if you are a person that sleeps deeply.
I would stay the Bridgefield again but use the Champagne Spa room which is upstairs.More
