AIRBNB FROM HELL - SAFETY THREATENED

We have read numerous reviews on AirBNB and always wonder if the best and worst are true. This one is. We want to do our best to make sure that no one else has the same experience we had with this host (and perhaps AirBNB).
We had 3 nights booked at this place. When we checked in, the condition of the apartment should have been at least a yellow flag: as usual, the place didn't match the glamor photos. We know that's an accepted risk with AirBNB. This one was further off than any of the dozens we have experienced before. The bathrooms are remniscent of a mobile home. The balcony "overlooks" a cramped alley despite the photos implying it overlooks the famous windmills and waterfront. A bucket still filled with dirty water and a mop was sitting in the middle of the balcony, cleaning supplies were left spread out, and long hair was on the living room and bathroom floors. I always go with my gut feeling, but it was peak season in Mykonos and we were planning to spend little time inside the apartment. So we let it go.
On day 2, when we returned to the apartment there was no running water - anywhere in the unit. None. I texted Stella, the owner, to which she responded that it was our problem, not hers. She said it was a municipality issue. She didn't even try to pretend to care. In both the AirBNB contract and the laws of decency, running water is a basic necessity that your host is required to provide (in addition to electricity and a roof over your head). After waiting for several hours for the water to come back, we told her we would have to move out and gave her an option to issue a refund for the remaining nights or book us a hotel room. Her response was threatening and terse...absence of water is not a reason for moving out!
After speaking with AirBnb (by the way, don’t rely on AirBnb “customer service” in the time of challenge!) we booked ourselves a hotel elsewhere (remember, it is peak season, it wasn’t easy!), packed up and as we were leaving the apartment, Stella showed up at the doorstep with a male "colleague". They launched a verbal attack. Then they physically attempted to restrain us from departing, and as we managed to get past them the male "colleague" started chasing us, screaming, cursing and physically approaching my husband in a threatening manner, getting so close in his face that I honestly felt that we were in danger! I have never witnessed anything like this in my life.
We have reported these people everywhere possible and believe that their profile should be shut down and they should be flagged for any possible attempt to rejoin AirBnb in the future.
I am also very disappointed how AirBnb agent handled the call that night. After an hour of waiting on hold, we were "helped" by an agent who could only follow a “script” and kept passing responsibility on to someone else, although you can never talk to that “someone else”. We were refunded 50% although we stayed only 1 night out of 3 nights booked. In my opinion, paying any amount is too generous for an AirBnb that is outright unsafe.
We and our family have spent tens of thousands of dollars staying with AirBnb worldwide. And although it always matched or exceeded our expectations, this entire experience and the way it was handled by AirBNB will make us dramatically more cautious in traveling with AirBNB in the future.
