We had a great stay!
Waitakere is a great option if you don't want to stay directly in Auckland. Close to both the West and East coast beaches, easy access to Auckland and Waitakere Park. Shopping nearby. Playgrounds with bbq / picnic area about 5-10min by car.
The house is located in very quiet surroundings. Parking right next to the house. Kitchen and bathroom are well equipped. Tons of games and books for adults and kids. Clean & tidy. Check-in was easy as the key is in a lock-box. Stan and Hannah are very friendly and gave us some good tips.
There's a nice backyard and small terrace. Just watch out for those pesky NZ mosquitos! :-)
