It probably beats the alternative of having a flatmate / boarder year round if you’re trying to bring down costs. For me I think the layout of your house can be important as to how comfortable you are with having someone else around.
We stayed on a farm just out of Hamilton because it was pet friendly and their room with ensuite was on the other side of the internal garage which I thought was ideal. Also had a tennis court, spa, and she would cook what you wanted – a very yummy cook! Wouldn’t surprise me if they’re on air bnb nowadays or NZ’s own holiday houses or book a bach sites. I think she advertised through AA before.
