Incredibly handy to get to CHCH CBD: with a 10-15 minutes walk you are at the Cathedral. This together with a covered car park make this location very useful for someone who wants to visit the city.
The apartment itself is old (sort of granma's flat - I mean it in a good way) but partly renovated (e.g. shower). Being old it does not have a centralized heating system (warmest spot is the living room where the heat pump is) but there are electric heaters to help warming up the rooms.
The only negative point to me is the club next door, which gets quite loud in the weekend evenings. It's a bit of a stress for light sleepers.
