If you choose to stay at Victoria's place, you will her to be a great and attentive host. Her place is light and bright, clean, in a great location between two interesting parts of Sydney including Darling Harbor. The balcony is a particular benefit and relaxing space.
It has a well equipped kitchen for a short stay apartment, including basic spices and olive oil and both a coffee press and coffee maker so you will be pleased if you bring food basics like coffee. The local IGA is a 5 minute walk if you are stocking up or missing that one item for dinner ingredients.
As in any urban area, birds and traffic can bring noise in the mornings, and will social groups out at night. If you are sensitive to noise, or used to the quiet countryside, you might bring earplugs.
The place is easy to come back to during the day to relax, refresh, nap and head out again, enjoy!
