My partner and I stayed at Ai's place for four nights at the end of our one month trip to New Zealand.
Ai was available and communicative through the airbnb app before and during our trip. She arranged to meet us at the front door of the building when we arrived, showing us how to get inside and orienting us to the apartment.
The apartment itself is as described and definitely perfect for one or two people. It was clean and comfortable and in walking distance of everything we wanted to do while in Auckland. We did take a taxi a couple of times due to heavy rains.
I would recommend this accommodation.
