Great location if you're just staying in Christchurch for a short period. It's really close to the airport and Peter picked us up from the place, where we dropped off our campervan and gave us a ride to the airport the next day!
Peter and Sharon were both really nice hosts and seem to be very interesting in meeting new people from all over the world!
The house is huge and the guest area just as shown in the pictures. Lots of space, very clean and tidy, with a private bathroom and toilet! We also got a great breakfast which was already prepared when we got up!
You can get to the city centre by bus, which takes some time and the taxiride back was pretty expensive, but if your main reason to come to Christchurch is the airport, I would definitely recommend Peter and Sharon's place!!
