Terrific place, in a terrific location. We followed 3 of Liz and Bruce's suggestions which included going to Piha Beach, going to Zap Thai food, and going to Doolan's Brothers. All were great!
The place was clean, convenient, and the hosts were fantastic before and during our stay. Just a note that one of the 'bedrooms' is in the kitchen/dining area. Didn't matter to us, but it might to some people.
Also, the place isn't ideal for a 'staycation' (or if the weather is poor and you're stuck at your AirBnB), as there aren't many areas for sitting and hanging around. But, perfect if you are going out to explore.
