We booked Helen and John's granny flat for a one night getaway. It suited us (couple in mid-30's, newborn and giant pooch) perfectly. The place is spot on as per description. It was just under 1km to walk into town or the beach. The granny flat has access to a huge picturesque backyard for the dog and/or kids to run around.
We didn't have much interaction with John and Helen but the interaction we did have was friendly/helpful and they seemed like lovely people.
Look forward to heading back. Great place. Great value. Thanks guys!
