Simon is a great host and provided clear instructions before and during our stay. He was very accommodating when we asked about a later check out. The hotel style fresh towels and linen are a nice touch. The apartment is close to town centre, good wifi and perfect for a few days as a couple or single. Heated flooring and portable heater were a nice bonus for the cooler nights and early mornings.
Cons - smaller than expected, very much a studio. As others have said the apartment is on a steep hill, but this isn't a big issue for everyone. If you have a car, keep in mind there is no chance you'll find street parking up the hill during busy periods (we were there during the Easter break). The plus side to being up the hill is the amazing view (from the street, not the apartment itself) and Queenstown is all about views!
Finally, some of the kitchen items need updating/ replacing and this has been communicated to Simon so this shouldn't be an issue for future guests.
