The house is great value for a family traveling to Maui, has all the amenities you need for a comfortable stay and are able to cook meals easily. I'd recommend you have a car so you can get around the island, only the beach and one cafe are in walking distance.
The home is part of a group of apartments, if seemed like the other apartments were older people, so are likely to complain to the office for the smallest offense e.g. Talking too loud on the verandah, taking a floaty for a child in the pool.
