We enjoyed our trip to Christchurch.
The property was pretty much as described. The living area / kitchen is spacious.
The description about access is quite detailed (ie the 30-40 metre path up to the house). Under "points to note" it states "not steep". I would estimate about 1:10 steep and, after lugging 20kg suitcases up the slope (Including steps), I found it hard work and looked forward to a cup of coffee once unpacked.
Sadly there was no coffee in the cupboards, unlike most AirB&Bs we've stayed at in NZ. There was a plunger for the cafetiere, but no jug to fit the plunger, so no means of making the coffee we had brought with us.
The property was tidy but could benefit from a good spring clean.
The single bed may suit a child, but unsuitable for an adult due to the nature of the single mesh support under the mattress meaning that it sagged and offered no support in the middle of the back and was uncomfortable.
But a lovely view from the house and balcony over the estuary.
And the price for the property was relatively inexpensive compared with the other B&Bs we've stayed at in NZ.
