We had a lovely 2 weeks in Frankton. The apartment has virtually everything you'll need for a self-sufficient stay; it's very comfortable with a lovely bright bedroom and a great shower room/toilet. We didn't see much of Mel and Jono as we were out and about a lot, but when we did meet they were extremely friendly, helpful and informative - Mel even provided us with two large golfing umbrellas on an unusually wet day!
Remarkables Park is only a 5 minute walk away, where there are plenty of shops, cafes and a large supermarket. You can also catch the bus into Queenstown from here, which run every 10 mins. Or if you're feeling energetic you can take the stunning Queenstown Trail along the lake.
Overall, a great spot, great hosts, and we hope to return to beautiful New Zealand in the not too distant future.
