Unfortunately my stay was quite disappointing.
In terms of location, the apartment was very conveniently located to arrive by Skybus from the airport and close to CBD, harbour, etc. easy to walk to everywhere.
In terms of the actual stay, our first room on Level 2 was generally clean and tidy inside however the balcony was covered in bird poo and overlooked a dark dumpster alley. The room was also quite run down - did not appear as in the photos. It seemed this was the same level as the laundry/cleaning as the corridor was constantly filled with bags of dirty laundry and garbage. Generally we did notice there was regular presence of cleaning carts, laundry, and garbage on all levels at all times of day.
With some convincing we were moved to Level 13 after the first night which was a better match to the listing, though missing a lightbulb in the bathroom and ironing appliances (was provided when requested). It appeared that AirBnB guests were considered second priority to others booking direct through Barclay Studio.
Bad timing that one of the two lifts servicing the 24-floor building was broken and apparently had already been so for two weeks which meant we often had to wait 2-3 times to actually catch the lift as they were constantly full.
Perhaps my experience was disappointing because I was expecting a traditional AirBnB where the apartment is personally managed by its owner. If I wanted to stay in a serviced apartment I would have booked through some hotel website instead.
