We stayed in Jo’s place for a week while in Sydney. We were very happy with it - its location is great, with lots of restaurants and cafes nearby, and a short walk to Kingscross train station and then straight into Town Hall (2 stops) in the middle of CBD.
Yes it’s compact but it had everything we wanted for a very comfortable stay. There were lots of nice touches - toiletries and basic essentials provided - and even a welcome bottle of wine! Communications were promptly answered. I would very happily recommend this to anyone coming to Sydney!
