After travelling the world for two years, this was so far the worst Airbnb experience we've ever had. A formal complaint has been submitted to Airbnb head office. In brief, host Massimo was abusive and harassed us at 1AM resulting in total restless night and absolute horror. We were then forced by Massimo to leave the flat because we reported him to Airbnb of his misconduct. Detailed facts: We checked in at 5:10 PM Venice local time and Massimo met us at the flat. He then immediately requested us to pay a tax fee in cash. This payment was not mentioned before neither in message nor listing description. Upon confirming with Airbnb Support, we were advised that we were not obligated to make any off site payment arrangements and any additional charges need to be done thru the resolution center. Furthermore, this payment, along with Massimo's demand on copying our ID, were not mentioned in any part of the listing nor messages. When we communicated this information back to Massimo, he became agitated and stormed out yelling in Italian, which we couldn’t understand. He later came back four more times demanding cash payment despite we repeatedly asked him to check with Airbnb first. He then forced me talking to someone on the phone claiming to be an Airbnb staff, whom did not resolve the situation either. Massimo then left the flat and never spoken to us again. Later that night at 12:52 AM, I received a message from Massimo demanding us to leave. At 1 AM, Massimo came to our flat drunk and trying to get in and rang the loud doorbell more then three times, waking everyone up. We did not open the door as we feared that he might do us harm, based on the fact that he appeared drunk walking back and forth mumbling just outside the front door. After a few attempts, Massimo went back upstairs and we could hear him walking heavily back and forth. In total distress, I called Airbnb Support for urgent assistance. I was advised to book a hotel for the second night because our safety was in danger. I did so immediately and by the time I finished the booking, it was 3 AM already. None of us slept for a minute that night fearing Massimo would come back again at anytime. We had all of our bags packed and dressed to leave in case the worst happens. We sat in the living room until 7 AM then we left the flat. Apart from all that, other problems were: 1. When checking in at 5:10 PM, beds weren’t made. There were still cleaners inside the flat trying to get everything ready, despite that fact that we told Massimo our arrival time one day prior. 2. Dishwasher got dirty dishes inside and does not seem to work. 3. Aircon doesn’t work due to broken remote control. We reported this back to the host, however no response. 4. All rooms were dirty and...
