I stayed at Ariana's place for around 5 days with my (senior) father, wife, and 2 year old kid. Ariana was such a lovely host and was very responsive and helpful throughout the whole process. She was also very understanding when my child threw up on the bed during our last night.
The place itself is tastefully decorated, and has all cooking essentials. In the cupboards, there's an assortment of condiments and other food items that may be used. The tap water from the kitchen is potable, so there may be no need to stock on distilled water for longer stays. The bathroom is functional, but with a few improvements it would be perfect.
The place is located at a prime area near public transportation (bus/train), restaurants, cafes, and supermarkets. You will find out about the specifics in the handbook that Ariana will provide.
To get to the place from the domestic airport,you can take a shuttle for $22 per person. It would usually stop at the corner of Orwell and Macleay streets which is around 15-20 meters from the apartment's entrance. Or you can take a cab which will take you right at the front entrance for $63.50. To get from the studio to the airport, you may wait for a taxi, or flag any airport shuttle that passes the street facing the entrance, or you may buy shuttle tickets in advance at the convenience store at the other side of the street.
Lastly, do note that there are around 15-20 steps on the stairway leading to the studio. Some extra effort will be required if you're carrying heavy luggage.
