Olive Hill is a wooden house in a beautiful setting. It's a typical "farmstay" style cottage. There's plenty of "outside" to enjoy, as well as all the basic features you'd expect. Set on a very quiet road but only 5 minutes/10 minutes for Margaret River (and 2 minutes from a local brewery!) it's a perfect base to tour the region.
My only negative: it's pricey - but comparable to other places in Margaret River as everything in the region is very expensive.
