Hi,

We stayed in Aspen House on our last few days in AKL last year, it was nice, clean and spacious. Slightly noisey as you're slap bang in the middle of the city but it was nice and easy to get to.

You can either get the bus from the aiport which is about 30-40mins as it's one of the last stops but it does stop right outside the B&B or you could get a cab which would be about 10mins I'd imagine, not too sure how much that would be tho.

Good luck at finding somewhere!
