We stayed at this place with not very expectations being local Darwinites. The crisp, clean interior, the spectacular views and the small touches like an emergency kit in case of cyclone went a long way to impress. The washing machine was somewhat dated and failed to work, which for a family of six was a bit of a problem. However, the were very responsive, its just unfortunate we were already on our way by the time the could fix it.
There were two undercover car parks allocated, this was fantastic because I could unhook the trailer and not worry about it getting stolen, damaged or towed away. It was very close to all the restaurants, pretty close (5 min) to the local Woolies and had a substantial size kitchen and refrigerator.
Overall, it was a very nice place to stay for a family of six and would strongly recommend you consider this as an option for your family.
