Our group of five stayed at Corey & Andrea's place in Timaru and it was a great experience that we would highly recommend to others.
The house has three bedrooms (enough to sleep 5), a modern bathroom, large kitchen, trampoline and games room for kids, and a vege garden (which we were able take tomatoes & strawberries from).
The hosts were great to communicate with, respectful of our privacy, and check-in was straightforward - they even left us a personalised welcome note, and a few goodies upon arrival.
We would love to come back one day, it's definitely good value for money.
