I stayed at Manita & Edwin's place for 3 nights. They have a gorgeous place in a suburban area of Rotorua, about 15 minutes from the City Centre by bus. It was a clean place, had everything you could wish for and - what I find very considerate - seperate boxes in the fridge for each guest to keep their food. They also helped me out a great deal with various questions and issues. They both know the area in and out and recommend things to do too.
I can definitely recommend staying in Manita and Edwin's place!
