I stayed at Nick's place while visiting Auckland with my daughters who are 2 and 3 and a half, I also had my parents joining me and my sister and her young family. Nick's place is fantastic for a family get together or vacation. The kids loved the outdoor playset and Nick was kind enough to leave out some extra toys for the kids to play with inside. Nick met us on our arrival and thoroughly, explained the house and the nearby area, also leaving detailed instructions/tips for us, while also providing a small welcome pack of some of the essentials required, we were also able to make use of basic cooking needs ie. salt/pepper etc. The house is very conveniently located an easy short walk to St. Heliers shops and beach.
I would very much recommend Nick's place, especially for those in a larger group or possibly 1 or 2 families staying together.
