I have worked in the travel industry for 37 years and am shocked to find such awful places advertised as hotels in Australia.
One of them is an air conditioner, an old type that penetrates the wall, but because the bottom is not straight, there is a large gap through which wind blows in 24 hours a day, 365 days a year, and we can hear everything, including the engine noise of a speeding car on the main road right beside us, as well as the sirens of ambulances and police vehicles.
Also, this air conditioner is covered in cobwebs and probably hasn't been cleaned for several years, so I have a feeling that the air it blows out contains countless mold spores.
Also, when I first entered the shower room, I found several strands of hair lying around. It seems that the room has never been cleaned. There was also several years' worth of dust accumulated on the ventilation fan, so it seems that the room has never been cleaned.
Finally, the family diagonally opposite, who seemed to be Indian, did not close the door, and the screams, especially of their children, continued for three consecutive nights until 1 a.m. We requested the receptionist to pay attention to them, but they never stopped.
