The host was great. Easy communication (App and email).
You can come and go as you wish. So ideal for those wo are arriving in/leaving Sydney (especially domestic) or might want to stay out longer.
Bus/train connections are very good too (~10 to 15 min walk from the Airbnb).
I did deduct a point for the location because the airplanes are quite loud. BUT I would expect someone booking an Airbnb this close to the airport to be aware of that!
We had a pleasant stay and it was perfect for our needs.
