My wife and me stayed at Annette and Westons place near Taumaranui for a week and never ran out of things to do. We really enjoyed our accommodation and it's view from every room of the nearby Wanganui River.
Special features included off the grid solar electricity and gas, central heating, a massive outdoor fire pit, with an endless supply of wood, between our unit and the river and an outdoor bath with an endless supply of hot water and it's own fire for cold nights.
Everything was very clean and our bed was super comfortable; we slept very well. All you can hear at night is the sound of the river flowing.
