This is a really nice place, stylish and small, but comfortable. Rachel is friendly and very responsive and helpful. Would definitely recommend this place.
The only notes that other travelers might find useful is that there is no heater in the bedroom (you have to move the space heater from the living area to the bedroom if you get cold at night), and that it's not easy to eat in the house as you can only clean dishes in the bathroom sink, or leave them for Rachel to tidy up (which she does offer to do, which is nice).
The location is great, very close to the city centre by car, and Wellington itself is a really nice city!
