Great place in a nice neighbourhood, with easy access to anything in Christchurch, and located close to a lovely park. The botanic gardens are a brief walk away, and you could easily walk into town in around 15 - 20 minutes.
The flat was very clean and comfortable, with a great modern bathroom and everything we needed in the kitchen. The bed was very comfortable and there was no noise from outside whatsoever. We could hear people walking on the upper floor, but this was fairly quiet and didn’t bother us.
Overall I would recommend this place to others, and we actually stayed twice on our NZ trip.
