The location is perfect and walking distance to almost anywhere you need/want as a tourist, shopping malls, groceries and attractions. The hosts are friendly and answer your questions in a efficient and timely way. The room is good for two persons (maximum), quite and bed are comfortable.
It would be perfect if the room can be cleaned and deorderized more thoroughly, such as cleaning the dusts left on vents and some corners.
Some moldy odor came out of the cabinet of washers and dryers although it did not bother us too much. Those could be improved.
In the hallway, you can smell some cooking from a resturant on the first floor. Sometimes, it was a bit annoying for some cuisine, but it did not get into the apartment and we did not stay in hallway too long (just waiting for the elevators) anyway.
In general, it is a safe and convenient place to stay during the visit of the Sydney CBD. I recommend it.
