Would 100% recommend Adam's place! It is spacious, clean, great location close to loads of buses/train links.
That's all before you get to Adam who is the perfect host, super friendly and always full of tips for things to do in Sydney and beyond! He was also really flexible in letting us stay a few nights longer when our plans changed at the last minute so we'll always be grateful to him for that. We would move in with him if we could! :)
