Jo and her husband were lovely hosts for the four nights I stayed at their place. Jo really went above and beyond, offering a couple short lifts across town as I didn't have a car.
The studio itself is pleasant, private, and exactly as described in the listing.
Regarding distance from town, it's a nice 35 minute walk through a calm neighborhood and park. If you're looking for a comfortable stay in Wānaka I would highly recommend staying here!
