We just happened to stay here during Tropical Cyclone Gabrielle (which was less than ideal), but Tyler was incredibly helpful and responsive throughout our entire stay, offering us any sort of assistance we might have needed as a result of the storm.
The property was clean, well-kept, and exactly as pictured/described in the listing. The studio is very close to Cornwall Park, has ample street parking, and is within walking distance of a number of shops and eateries. It's fairly well-located within Auckland, so you can get just about anywhere without too much fuss.
The only thing potentially-lacking for your trip is air conditioning in the unit if you're traveling in the warmer months, but you can open the windows and air the place out fairly quickly; you should be out exploring Auckland in the middle of the day anyway, though!
