We have been hosting with Airbnb for two years now and have had over 400 guests (we live near an airport in the UK) from 30 different countries. There have been mostly very good experiences but obviously with over 400 guests you do meet a few weirdos. This one booking was for six weeks for a guy living in Australia coming to the UK for a training course. He was an aircraft engineer and very nice guy in general. However, I noticed from the first day that he seemed to have an issue with using the cutlery, cup, and spoon provided in his room and was downstairs in the kitchen, i.e. washing the items then cleaning them quite thoroughly. I thought this was very strange as we make sure everything is spotlessly clean. A couple of days in and he was asking for more toilet rolls to be put in the bathroom as he was going through at least one a day. It seemed like he had a cleaning fetish of some kind or a compulsive cleaning disorder.
Anyway, we had to go to our property abroad for a month and left him alone in the house (our part of the house we can keep locked so he only had access to the kitchen, bathroom, and garden). On our return he was due to leave in a few days but on the last day asked me if I wanted to keep the cutlery, plate, bowl, and mug that he had purchased new because he did not need to take them back to Australia. He obviously did not want to use our items and we found this to be incredibly rude, to say the least.
Another time we had a young girl arrive for three weeks with a large suitcase and a big box full of cooking pots and herbs, spices, and food. This girl was cooking Indian food twice and sometimes three times a day because she didn’t want to eat food from the supermarket. The house stunk of Indian food for the whole three weeks and I was having to apologise to our other guests (as we rent two rooms in our home) every day due to the smell. Lastly, we had a girl stay for a couple of weeks and she had to be told to stop using the kitchen at midnight. She was always cooking (like a frying pan full of eight chicken legs) late at night and the smell would move throughout the house, even into the bedrooms. Since the last guest, we added “no cooking after 8:00 PM” to the house rules.
