We thoroughly enjoyed staying at Karen's red house. We have never stayed around Mullaway but it was absolutely unspoilt and gorgeous. There are great restaurants and cafes with good coffee in Woolgoolga which is only five minutes away.
Karen's place had everything that made our stay comfortable. A heater in every room, plenty of doonas, fast wifi, lamp stand, power point to charge our phones, great shower, clean towels, and a great and well equipped kitchen. You will definitely love staying at her red house!
