We enjoyed our stay in Karori. We came as a family and the place is nice. The house is very clean, comfortable, and functional. It has everything you will need and the washing machine and clothes drier are top spec!
The highlight for us though has to be the location : 5 min walk to supermarkets, shops, restaurants and city buses, as well as parks and playgrounds. Everything you need to have a good stay in Wellington
If you have little ones, they will sleep in the double bed and you will have to be a bit careful with the dining room furniture. Great big bath.
