Jos house is the best place to stay in Christchurch. It is like a paradise in the city. Her garden is amazing, her cats are lovely and sometimes even ducks came along. A lot of restaurants are in the neighborhood and to the park and the city center its a half n hour walk or a short bus drive. The guest bed is too comfy, you don't want to stand up in the morning.
Unfortunetly we didn't met Jo, but her housesitter Bridy was also very kind and helpful.
Only thing to know is that she has two guest rooms and sometimes (in our case) private guests as well. So we were not alone in her house and kitchen and bathroom is shared. We did not expect that, but it was fine.
