We just stayed for one night on our way from Melbourne to Twelve Apostels and back. Therefore staying in Port Campbell is perfect - just 10km away from Twelve Apostels, which enabes you to watch the sunset as well as sunrise there. Port Campbell is a small town, but offers everything you need (several cafes, grocery store, pubs,...).
The room was okay, but not one of those shown in the pictures (except the terrace on picture 31). Our room was rather old (especially the bathroom and kitchen area), but as said really ok for on night.
As we stayed there beginning of May it was good that the AC was also able to heat the room, otherwise it would be quite cold.
Parking spots are available for free. WIFI is included.
Staff was really really friendly.
