Bed: I slept fine in it, not much else to say.
Location: Close to Kings Cross station, on the other side of William St. Good for anything between the CBD and Bondi inclusive. Trips further afield often require a change of train at Central.
Noise: Some noise from the street that closing the balcony door (which fortunately has a flyscreen) and window kept out well enough.
Bathroom: Clean and functional
Kitchen: Small and functional. It had enough utensils/cutlery/crockery for my cooking needs. The oven needed to be cleaned.
Dining Table/Desk. As advertised. One day I will stay in a place with a great dining table/desk, but this was not that day.
TV: Gets all the channels (not guaranteed in Sydney!)
Couch: It's a sofa bed. So it's never going to be as comfortable as a standalone couch. But I knew that going in, and you should too.
The washing machine came in handy, and there's also some books with tourist information in them that you can read.
Internet (wifi): Worked perfectly, good speeds for both upload/download.
