Do not be deterred by Mary's many rules ;) this keeps the place clean and orderly for all guests. Mary was very accommodating when our flight was delayed and we were not able to meet at the prearranged time to share keys.
We had no issue with the cooking rules though I love bacon because the place is so walkable to the local restaurants and bars. We choose to eat out to experience coffs.
I would recommend renting a car if you want to see more of the area u can see so much of the coast if ur willing to do a few 15-20min drives up or down. We were there just for a quick weekend but we managed to see the Skywalk, diggers beach, and the memorial pool in sawretto in a day. If you opt not to rent a car you will find it easy to walk to all of Coffs harbour from Mary's home.
We would stay again :)
