We stayed at Gary & Emily's place for 31 days. The place was great - it's not too far from Queenstown and is only 4 minutes walk away from the bus stop to get into town. Buy a Go Card and you can get into town for just $2. Buses come either every 30 or 60 minutes, depending on time of day so you'll need to time it properly. You can also get a lift up to Coronet Peak for the ski season at the same bus stop, so it's really convenient for that as well.
The kitchen is well-stocked with everything you'd need. Large fridge and plenty of cupboard space. They also gave us some free beers as well as some eggs from the chickens they keep (you can't hear them making any noise, even with the windows open, so wouldn't worry).
The TV is pretty big and the living room sofa is pretty comfortable.
WiFi was very fast, I believe upwards of 50Mbps so much better than most places in New Zealand.
The bed is very comfortable, and extra bedding is provided if needed. Lots of storage and hanging space for clothes.
The bathroom was nice too. Could maybe have done with a proper door that closes (there is a sliding door, so you still get privacy. Shower was decent - has both a normal shower and a ceiling shower, depending on your preference, with all the toiletries you'd need provided, along with some sun cream, bug spray, etc. Washing machine is in the bathroom as well and they provide detergent.
It's got four windows in total, including the bathroom and is much brighter during the day than you'd expect.
Heating during winter was good. Takes a good few hours to get going if you turn them all off but once it's warmed up it'll keep warm.
Stairs coming down to the apartment could be a little slippery when wet so would be a bit careful.
Despite having a newborn we could barely hear anything coming from upstairs with the exception of an occasional footstep during the day. Never heard any talking or anything else. No other background noise coming from outside either as it's pretty remote and far enough away from the main road.
