This ranks as one of the worst travel experience I have ever had. Isabelle emailed me the day we were due to arrive in Paris and said there was water damage to our unit and we could not stay there. But no worries, she had a better place for us to stay. She did not cancel through Airbnb and could not show me the other unit on Airbnb because it was an apartment "she kept for friends in Paris". Nobody keeps apartments for friends in Paris, so I was doubtful from the beginning. The unit we had originally booked had 5 beds for our family of 5. The unit we were shown had 2. I objected and asked for a discount. Michael, the man who met us and let us in, became very angry and said if we didn't want the unit "no problem for him", he would cancel the reservation. Then got on the phone and pretended to call someone to cancel it (I speak enough French to know he was faking the cancelation). In any event, it was now 5pm and very cold and I had a tired family with 3 kids and I did not want to be on the sidewalk trying to find new accommodations. I told him we would take it for the night but would have to discuss next steps. Frankly, we would probably have made it work if they had been willing to offer some modest discount. But both Michael and Isabelle insisted it was a better unit. Michael then tried to get me to sign a piece of paper to "acknowledge receipt of a second key". It was, in fact, a contract to stay for all 4 days at the rate of the other unit. Again, in violation of Airbnb rules. I refused and he started yelling at us some more while he grabbed the second key and stormed out. I started looking for another unit that evening and made Airbnb aware of the switch and my concerns about a very hostile lessor. Unfortunately, Airbnb canceled the unit in the morning before we were awake (being 7 hours behind Paris time). I told them to call Isabelle and have her tell Michael NOT to show up. She agreed and we started scrambling to find another unit. Meanwhile, Michael showed up anyhow and this time was exceedingly agitated and screamed at us to get out. It was after 11am and he said he had to clean it for the next renter. How had he rented it so quickly when we just canceled and he thought we'd be there for 4 days, I asked. "Not my problem" he screamed back and came within 6 inches of my face. All the while wearing full leather outfit and keeping his motorcycle helmet on, no doubt to look more menacing. I stepped back and put my hands out and told him to back off. "If you touch me, I'll kill you", he said with a raised fist....
