We were at Stu's place for just a couple of days and had a great time. You'll have your own bathroom and entrace so you'll feel the privacy of a 'entire place' while renting the room.
Stu was great as well, we arrived a bit later than expected and he had no issues with extending the check in time for us, communication was great and he's good fun. The apartment is just 7 minutes to Queenstown by car or 15 min by bus (5 dollars) and another 10 minutes to the airport.
We will come back for sure!
