The room is located next to good restaurants and a good grocery store for food options. I recommend Basil Thai on the corner of Valley and Dominion.
It's close enough to the city and the airport to get reasonable Uber fares for both directions.
It's also conveniently located near Mount Eden, which is worth the hike to see the entire view of Auckland. On your way down, grab some food at the cafes in Eden Park.
If you come in the middle of the summer, be prepared for no air conditioning and very sunny windows. We didn't have a problem with it since the weather was mild during our visit.
