We had a nice 2-night stay at Rooftop apartment. Superb location in the heart of Margaret River, close to shops & restaurants etc. The kitchen is well equipped and the living room is a great space with the high ceiling and balcony. Bedrooms and bathrooms are comfortable and good size too.
The only downside were noises outside (traffic, loading/unloading) early in the morning, which can wake up light sleepers. But that's what you get for such a central location, worth it for us!
