The Malcolm's place had the very clean and lovely rooms and perfect bathroom as well. His hospitality was beyond my expectation as he kept asking us if we are okay or not, and also chatting with us every morning over the breakfast which made us relax and feel like being home. He even took us to see around the great place in Auckland.
Regarding the location, you can take a bus to get this place from the CBD. If you stay more than 3 days, I recommend you buy the AT HOP card as paying the fee in cash is almost twice as expensive as using the IC card which costs $10 to get initially.
As it was my first experience to stay with Airbnb I was little nervous, however it turned out the great memory of Auckland by their warm and nice hospitality. I definitely want to come back!
