I had a lovely stay at Kimi's apartment. It's clean, suitable for solo travellers and has a beautiful view!
Pros: Beddings were clean and comfy. The apartment is located in a great area, just a few mins from the train station; you can go to the city/anywhere easily from there by the 4 lines. Kimi and the team had excellent communication skills, and they respond quickly! The area is nice, and you can find shops and restaurants just 5 mins walk.
Cons: Trains noise was within the normal ranges for me. Also, you could hear neighbours' door sounds, but it's not that bad. Placing a carpet could reduce the issue! Finally, the extra/ single bed could bother some people, but it was okay for me.
To sum up, I recommend Kimi's apartment and would come again if visiting Sydney!
