Alan is a great host, very welcoming, and as he said to me 'it's like staying with friends' which captures it in a nutshell.
The apartment is a good walk from centre, but I made sure I walked there and back every day. There is the public transport system if required.
The apartment is very clean and tidy, I came and went freely at all hours, and never heard Alan either in the evenings or the mornings. It was great value, and I wouldn't hesitate to recommend it for a great value place in Sydney.
