We stayed for a week as a family with 4 adults and 2 young children. There was plenty of room and the bedrooms are a good size.
The house is very convenient for going up to Coronet Peak each day, though a little way out of town itself, so you need to drive in for groceries etc. However it is a lovely quiet spot with a nice outlook and a playground and walkway nearby.
The house is very warm with central heating and a log burner and the kitchen is well set up with essentials.
I would suggest bringing your own games/ pack of cards if that’s your thing as there wasn’t anything like that in the house.
