Greg's sleep-out is good value for a short stay in Christchurch. I had a car with a GPS, and had no problem finding the address in a well-established and quiet neighborhood, next to the Greek Orthodox church. The room is attached to the garage at the back of the house, with a window towards the backyard. To go to the shower/toilet, one passes through the laundry room, hence all the listing notes referring to the laundry. The laundry sink is used as a bathroom sink. Everything was clean and functional, and it was fine for my one-night stay alone; it's difficult to imagine two people using it, as the space is minimal.
Greg kindly provides coffee, tea, a kettle and milk in the fridge.
