The description on Airbnb is accurate. The offering is the back half of the house. There is a door on one connecting passage, and a folding divider is across and closing off another connecting hallway. As a result of this non-permeable "dividing off", there is noise (dish clatter, etc.) that travels from their area to ours - and vice versa. This did not bother us. We quieted down at night about the same time as our hosts, and we did not run the washing machine after 9 p.m. as they requested. It helps that we are quiet people. Also, being two older women travelers, we felt safer knowing someone was nearby.
What we received amply for a budget price - was a great deal of space that does not usually come in this budget range in a resort area. We each got a bedroom, blessed with extra blankets should we need them; and there was a large, comfortable sitting room with sofas; a small table and two chairs; a low-slung fridge and dishes in the corner; and the tv--- plus a sliding glass door to the patio and garden area.
Amenities were bountiful! There wasn't anything Jo and David hadn't thought of. The television was the largest and easiest to operate of all imomm nn our trip. We could use beach towels; shampoo; hair dryer; etc.
There was a bowl of fruit and some candies awaiting us in addition to standard self-serve breakfast items. A special treat was that we were provided fresh eggs from chickens in the back yard.
There is a microwave but no stove inside the Airbnb. We were welcomed to use the Weber grill outside to cook the eggs. David showed me how to use the Weber grill, and away I went!
The location was fine for us even though we did not have a car - we walked back and forth from town. A local tour company picked us up - and dropped us off - for a half day wine tour.
What was unique about this Airbnb was well-written signage. We like signage since it can very effectively relay host expectations - and thus help avoid misunderstsndings.
If you are very quiet, respectful travelers - this might be just the place for you. Depending on schedules, David and Jo are willing to help with transportation "to and fro" the Margaret River bus station.
If you have any questions, use the "contact host" feature before booking. Jo is extremely skilled in her written communication, and she is very quick to respond.
