Alan and Elaine are the most hospitable people I ever met. I didn't feel like I was a house guest, I felt like I was a part of the family. It was excellent for an extroverted solo traveler like me. It may be a bit too much attention if you are introverted and like your space, but the room does have it's own entrance from the outside and I'm sure they would respect your space as well.
The room itself felt like a 4-star hotel set on top of a hill overlooking some of the most beautiful countryside imaginable. The only issue is that the residence is about a 10 minute drive from Taupo itself, and there doesn't seem to be a good way to get there through public transit. But if you have a car, I would hands down recommend this place for a solo traveler over any other option!
