My wife, our daughter (4 years) and I stayed at Rachel's place for four nights and absolutely enjoyed our stay. The guesthouse itself is spacious, clean and has everything you need. However, the main reason to go is the property it is situated on: a beautiful place which feels like it is in the middle nowhere despite being only 5 minutes off the Great Ocean Road and less than 10 minutes away from Apollo Bay (by car). We, especially our daughter, loved all the animals and the gorgeous scenery - we even saw a koala in the garden one evening. In addition, Rachel and her family were the perfect hosts: warm, friendly and helpful - her husband and kids even took us with them to the beach.
Please bear in mind that there is no mobile reception on the property and no wifi in the guesthouse. This was absolutely fine for us, but there might me people who think differently.
Overall: highly recommended!!
