My wife and I stayed in this unit and had a great experience! The check-in process was a breeze, and the host is great at really timely communication. They also provide a book with tons of local recommendations and information, which was really helpful.
We stayed in the lower unit. There's a larger unit up above the one we stayed in. There's not a ton of insulation between the floors as we could hear our upstairs neighbors walking around the unit. It wasn't obsessive or deliberate, but just something to note in case you're planning to stay there for a few days.
It's about a 10-15 minute walk to town (all downhill)...the walk back is pretty aggressive so we normally took a taxi. If you don't have cash, you'll pay an extra $2 fee to charge a credit card everywhere in Queenstown.
We would definitely stay here again - great views from the unit and the hot tub was a great amenity.
