If you want to stay in the city centre of Auckland in a comfortable flat I can highly recommend Jack's place. It's just a 5-7 minutes walk to shopping at Queen Street and perhaps 12-15 minutes to the waterfront.
He is an absolutely friendly guy, an awesome host and I really enjoyed staying in his flat. If you have any questions he would always be available to help you.
His apartment is very tidy and clean and well-equipped. Your room, the guest's bathroom and the complete flat is spacious and there are big windows that leave in the sun light. You can use the kitchen facilities (he even labelled the cupboards) and washing/ dry tumbler as well, but naturally are expected to keep them tidy and clean as they are.
Jack, I really enjoyed staying in your flat and thank you for your help! :) You are a good host! It was also a pleasure to meeting your father.
If someone from my friends wants to visit Auckland, I will definitely recommend your flat to them! Cheers :)
