The check-in process could not have been easier - Jenny provided the directions as soon as I was confirmed and I was able to drive up and check myself in on my own schedule. The location is very peaceful and while attached to the rest of the house there are no shared walls and both entrances are separately locked so the bedroom is very private. The room itself is spacious and has plenty of lights and outlets, etc. It was perfect for a quiet place to spend the night as I spent a few days visiting friends and touring around Auckland. I would definitely recommend, especially for on-the-go travelers!
My only notes of caution are that the location is in a quiet, residential neighborhood and the driveway is difficult to see at night. That said, it was very close to the state highways and made it very easy to get back and forth from anywhere I needed to go since I had a car. (As a small bonus for drivers who will return to the airport, there is a 24 hr gas station super close by where you can fill up before leaving.)
