We travel a lot with our kids and this is by far the best place we have stayed at.
The cottage/1 bedroom apartment itself was private and super clean, modern and tidy. It had everything we needed with a full kitchen and washer/dryer. Plus a lovely private deck with great outdoor seating.
The backyard was a dream for our children (primary school) and ourselves as well. There was an amazing treehouse, flying fox, sand pit, trampoline, play structures and so many different zones/area to play in- they enjoyed themselves for hours which meant a lovely peaceful vacation for us adults. We spent the mornings relaxing and the afternoons visiting all the neat places nearby- Remutaka Cycle trail, Rivendell and even took the train into Wellington (we could easily drive as not too far but was a fun adventure on the train and thus didn't have to deal with traffic or parking). This place was a wonderful retreat away from the city but a fantastic spot even if going into the city. The hosts were also super helpful but also respected our privacy and great communicators.
