Myself and my 2 boys (aged 12 and 13) stayed at Hayleys place in June 2017. Hayley and her family are lovely people, and made us all feel very welcome. The unit is in a central part of Christchurch in that you can access both the east and west relatively easily. The buses are close by so you can make your way into the central city without issues.
The unit itself was lovely. Everything you could need really. The bed was super comfy and the shower was gorgeous.
Hayley and Nigel have gone to a lot of effort to ensure comfort, and I would highly recommend it to others.
