My wife and I flew into NZ and stayed in Sharon's fully furnished and equipped "Granny Flat" on a very quiet crescent street for 4 weeks in late 2022.
Sharon lives upstairs, is very approachable and willing to chat.
The flat is very clean indeed, truly self-contained, and has a dedicated off-road parking spot. There is a shaded concreted area with garden furniture and a lawn.
20 min walk away is the Botany mall.
Internet connection speed (Mbs) is variable. We encountered best 103 down & 71 up; at worst 14 down & 6 up.
There is a portable, electric, oil-filled heating radiator. No air-con.
I had the impression that the neighbours (finally!) bought an anti-barking collar for their yappy dog. Just hope they remember to replace the battery when it's required.
We advanced our arrival date and, later, extended our leaving date. As the flat was available, that was fine with Sharon.
We enjoyed our stay and would happily stay there again.
