I stayed for nine nights at Gareth's and Patty's home and had a really good time.
They were both super friendly and very helpful in giving tips what to do in Sydney etc.
The flat is also really nice and not far away from Newtown or the Central.
If you are looking for a Airbnb flat where you can stay with kind, chatty and funny (etc.) hosts I would highly recommend staying at Gareth's and Patty's place!
