We really enjoyed our stay in Nicola's Bach. It is tidy and spacious (I stayed there with my wife and daughter).
Good kitchen, fast internet, good beds, nice garden: perfect stay.
Excellent location to visit the National Park and do Tongariro Crossing.
Unfortunately we didn't meet Nicola (she lives somewhere else) but she was easy to communicate with and responds very fast.
For future guests: please keep in mind that you are expected to bring your garbage to the disposal station 5 minutes away. You have to separate it there by hand so make sure you schedule in some time for this.
