Linda is correct about the booking process. She assured me that I would not have to worry about her husband and his co-worker bringing any tiling mess into my apartment. Upon arrival, I went over the apartment details with Tu, his partner spoke no English, so I asked that the info be relayed to him. That evening before bed, I checked the foyer door to ensure it was locked, it was ajar. The following morning after the guests left for work, I discovered that the foyer door, although properly closed, had been manually unlocked. I sent Tu a text asking if they had slept well and found the apartment meeting their needs. I also mentioned how I had found the door on both occasions and the importance of it remaining locked. The response I received was positive on the apartment and struck me as flippant on the door issue. As a host, having a sense of trust in your clients is very important and knowing that they will respect and take proper care of your property is as important. I did not get that feeling and therefore checked on the apartment, which I normally do not do. I was shocked to find feces splattered on the bathroom wall in several places. I called Airbnb to ask what my options were with this client. They immediately got a mediator involved and recommended all communication go through the Airbnb thread. That is when Linda got involved, first reacting with shock, denial and hostility and that is how she continued. The mediator spoke to both myself and the client separately. I told the guest to let me know when he arrived that evening and I went over the door operation with him again and showed him the bathroom wall. Again I was met with hostility and denial and refusal to clean or maintain my apartment until just before check out. What people seem to forget is that they are paying for the privilege to stay in your place; they do not own it and are not at liberty to mistreat it at their whim. The mediator told the guest he was responsible to clean daily, especially when there were accidents, and that I had the right to enter the apartment daily to check as a result of their behaviour and attitude. Again, people don't seem to realize, hosts are putting everything on the line and have a right to stop property damage and misuse. I was assured by the mediator that they would comply. I did not speak to or see the guest over the next days, as they left early, (7:00 am), and returned late, (7:00-8:30 pm). The door was left ajar two more times. I said nothing. I sent a text to Tu at 8:30 pm one full day before check out asking at what time that would be. I received no reply. To keep record of communication, I emailed through the Airbnb thread, remarking on the door again and asking for a response for check out. Again, I was subjected to Linda's verbal belligerence and personal attacks. This is business, people need to book places that are appropriate to their needs and lifestyle. My listing is a high-end, luxurious, private apartment in a historical district. I have had consistent five star reviews and have met and surpassed Airbnb's Superhost criteria. I do not judge my guests by occupation or nationality, and find it appalling and slanderous to be accused of such. If I felt that way, I would not have accepted many bookings, including this one. To conclude, Tu and his co-worker left the kitchen a complete mess, every surface covered in grease and food debris, many dishes, pots and pans returned to drawers filthy and wet. Needless to say, this required much more time and thoroughness to clean. And Linda is correct, this was a horrible experience for me. The disrespect and disregard of property and security, the hostility and belligerence, and general attitude of righteousness about misusing someone else's property exemplifies poor behaviour and describes the type of people I dealt with.
