This was our true experience. We finally stayed for 3 nights out of our initially scheduled 5 nights and moved to a nearby ibis apartment for the remaining 2 nights in Melbourne.
Apparently there was sewage problem in this townhouse (converted from an old warehouse). We did our showers and laundry as usual. In the 3rd evening at 19:00, the neighbour inhabited downstairs banged on our door, threatening us to open the door. We did not know these people and we were scared. We tried to contact the host but in vain. We called the police (we learned the number 000!) and waited for 20min. The banging continued. The host called back. I asked her to do something to help us. She replied, 'no, we are out of town.' I requested her to call the police and she claimed' "what am I supposed to tell the police? Pls call the police yourself." Feeling helpless, we could not but put up with the door banging for another 30min... Since the sound proofing was non existing, we could hear the neighbour talking loudly till 22:00 at night.
The next morning, when we went out for sightseeing, we were confronted by the neighbours who complained about the dirty water leaking from the airbnb place into their townhouse downstairs. She threatened to call the police. Finally Brad, the handyman was sent by the host to look at sewage problem etc, but could not find the apparent source of the water leakage. Essentially we need to return to the house from sightseeing to wait for Brad to come when he called. (the host did not inform us to wait beforehand!!) We made the best decision to move out at noon as we being visitors had no intention to be involved in this long lasting conflict between the neighbors and the host. We had 2 excellent quiet nights in the ibis apartment nearby.
I don't want to mention any negative comment. The above illustration was the actual scenario we experienced. Dear guests, please kindly decide yourself whether you wanna stay in this place.
