Turangi is a lovely place to stay, close to hot water pools, white water rafting, the Tongariro Alpine Crossing (and trout fishing, if that's your thing). Phillip's house is located in a quiet residential area just a 10-minute walk to the centre of the town (in which we recommend the Cadillac Café!).
The unit we were staying at was a welcoming and very clean place with enough space to move around and everything we needed to cook, we were there for a month so appreciated this. It can get quite cold in the wintertime but we were provided with heaters and blankets that made everything alright.
Phillip himself is a nice, friendly and helpful host, and we also got to meet his dog Bella who's a total sweetheart.
So in short we strongly recommend this AirBnB, and we would definitely stay there once more if we pass through the region again!
