Beep. This is the noise we heard every 30 seconds for a week. beep. We searched for three days to locate the exact noise from the unit, stairwell and the neighbour's unit. We spoke to the neighbour. It was a smoke alarm and it came from two "phantom" places in the unit and stairwell. We changed the battery at a cost which was re-imbersed later after we left and after being annoyed with the landlord. Beep. Polly the host, acknowledged that there was an issue and had a rude electrician in, who entered, changed the smoke alarm, and didn't wait to listen to the problem, and still it went beep. pause. beep. We had to leave the unit all day every day to get our work from home done. beep, and we had no sleep. beep. The bath is great, the bed is great but it wasn't relaxing. beep. we tried to no avail to leave to another Airbnb but there wasn't much available. beep. we communicated all the time with the host. beep. We believe the host Polly and her landlord new about the issue, but couldn't find the problem. beep. We asked for 50 percent discount which was approved, but not given yet. We were told there was no more beeping, as it didn't exist. beep. We were blackmailed into leaving a truthful, good review, and the decision to compensate was revoked and reneged. beep. The unit is clean. The neighbours in the unit next to the block were loud and obnoxious, with a baby crying. beep. I have daily migraines, and lots of pills. beep. There are no balconies to the unit. beep. Campsie is great for food choices, but not so good if you need a cafe. beep. Eventually Airbnb did compensate half of our stay, and the host gave us 62 dollars for the battery and our compensation. beep. not sure if you can handle it? beep.
