I had a terrible stay at this listing.
When I arrived, I realized Bonheur had never sent me the lockbox code. When I reached out to him, it took an hour to reply. It was freezing outside so I had to leave and stay with a friend the first night. Bonheur later ended up sending me the code to the apartment, with an apology.
When I got into the apartment, it was quite cold and no hot water. I spent 2 nights with no heat or hot water. By day 3 or 4, I let Bonheur know that the heat wasn't working nor was the hot water. He responded hours later that he'd have to ask the building manager, but never followed up. I asked him what was going on with the hot water and heat and he finally replied, that he hadn't heard from the building manager but asked "Are you sure there's no hot water or heat? The last guest complained it was too hot!"
I ended up leaving early with no partial refund. Bonheur was rude and unresponsive, and this experience has convinced me to stop using Airbnb as a product.
