What a lovely surprise. Would recommend.
Two couples each got bedrooms with ensuites, then there were still two other bedrooms with double beds and bunks all very close to the 3rd and main bathroom. Our kids slept upstairs in the rumpus on the 3 futons, they loved it. The kitchen was basic but had everything we needed, and the location was a 5 min walk to the beach and 5 min drive to Busselton. Bbq, washing machine and open fire in the main lounge room.
