We highly recommend Gunawan's and Indra's guest house for your trip to Sydney. It is very clean, quiet and cosy, and you can see that Gunawan and Indra put a lot of through into what their guests might need. The kitchen was much better equipped than any Airbnb I have stayed at. The place is perfect for a longer stay (we stayed a bit more than 2 weeks) as the dishwasher and washing machine add extra convenience. I also liked the decoration and chosen colours which are very tasteful. We really enjoyed our stay!
