Love self check-in because this allows flexibility with arrival times & no need to worry about delays. Very detailed (with pictures) instructions on how to locate the apartment & check in. Free parking is rare in Sydney, so this was great! The location is good also - easy walk to Darling Harbour & Chinatown with even kids & grandparents. If not up for walking there’s also the tram line across the street. Woolies just a block away for groceries. Nothing to complain about. Host was also sending messages to check in on us which was nice to know she was available if there were any issues.
