You're paying for the view, and what a view.
The property is a lightweight structure in above average condition, accessed by external stairs, above the owners garage, approximately 6m offset from their house. Access is via external timber stairs onto an upper deck. The accommodation is situated amongst the owners spectacular gardens.
Visual privacy is more than adequate, certainly more than a hotel or adjoined structure. Acoustically, as the rental sits on top of the garage, you can certainly hear it when the owners park, but that was limited to once or twice a day and was not bothersome or intrusive. The owners are clearly conscious of personal space and did not intrude or pry in any way, and were very nice. They have a lovely dog, which we barely saw, which cannot enter the entry stairs to the unit, as there is a gate.
The inside of the rental is exceptionally clean. The bed and bedding are high quality and very clean, though the doona was extremely warm, with limited alternatives. There is reverse cycle AC unit in the living section only, and air circulation to the bedroom was limited. In winter this was more than adequate, but in summer, I'm not sure. The remote is kind of broken (or perhaps running out of batteries), and so it was locked to 25C. Towels in the bathroom were great, and the hot water was faultless.
There is a full fridge and freezer (not a bar fridge), and a Nespresso machine, complete with some pods as well as tea, which is nice. The oven is a counter top electric one, not a 600mm built in, which may affect people planning to cook anything large.
The furniture is fine, mostly an assortment of cost effective and eclectic pieces. The lounge is a tiny love seat, which could be bigger, the chairs wicker or plastic and are outdoor furniture so not the most comfortable. Given the price range, easily comparable to 5 star hotels (minus the view), the furniture could use an update in style, size and comfort.
TV was fine, though it has terrible sounds, though with that view, you likely won't turn it on. A bluetooth speaker is included which is nice.
The deck is large and there are chairs and am umbrella, but we didn't use either due to the weather.
You pay for the views, and you get that in spades. Everything else is fine and comfortable - we will likely return.
