We stayed 3 days in Taupo, and loved having Abbie & Simon's studio as home base. Though it is a studio, it is set up to be really spacious, and we didn't have any problems. Perfect for a couple or small family.
The location is also great—just a short drive from a local grocery store and the city center, where there are a lot of cafes and restaurants to visit. The hosts also put great care into providing recommendations. Additionally, great spot for day trips to Rotorua and Tongariro National Park.
There was no sink, but we didn't have that much of a problem cleaning up, as we didn't eat in that much.
