I stayed at Penny's place for three months while visiting Sydney for work, and I can only highly recommend it! Penny is the perfect host and my stay in Sydney would have been much duller without this experience! Penny and family are friendly and helpful, happy to give advice in regards to Sydney, and really make you feel welcome in their home.
The room was nice and clean, providing the necessary amenities for both an out-going lifestyle as well as eating at home. The location of Penny's place in regards to reaching the CBD/central is perfect, and while initially reaching the eastern suburbs might seem difficult, both the T4 from Arncliffe as well as busses from Wolli Creek provide connections eastward.
Penny's place is a fantastic opportunity for any Sydney-bound traveler, and I can only recommend a stay there! I will be coming back when I make future returns to Sydney!
