This room represents exceptional value, probably the cheapest private double room you can get in central Sydney.
The location is convenient (a short walk from a train station, and the University of Sydney where I had a conference), the bed is comfortable and the large TV with free Netflix is a nice bonus.
I notice some other reviewers complained about the shower - it works fine, but getting it to your preferred temperature may require some adjusting with the taps.
It is (as is noted on the listing) an old building, so don't expect perfection. As you would expect for a room above a pub on an intersection, it can be noisy at night, particularly on a Friday or Saturday night. Earplugs or noise-cancelling headphones can help, but if you're a truly light sleeper, I'd look elsewhere. Otherwise, you're not going to find better value anywhere in central Sydney.
