Caveat: This unit is incorrectly listed as "entire house." It is actually a private bedroom in a suburban family's home.
That miscategorization aside, John and Maggie were tremendously friendly, and John picked me up from the bus stop, and dropped me at the airport, which was very generous and well beyond expectations. The space itself is clean and comfortable - it is a first floor bedroom and bathroom on the first floor of their house, accessed through the home's front door. I also appreciated the small touches, including instant coffee and a few snacks available in a mini-fridge in their laundry room, on the same floor.
Apart from the listing issue, the only real downside would be location - the house is located in a suburban neighborhood a good long walk (~45 mins) from Taupo's central area, so may be a better fit for travelers with a car or bicycles. That said, it is walkable, and the lakefront is only 15-20 mins down the hill. All-in, I enjoyed the stay, and it was a pleasure to meet the hosts and their son.
