Lots of people live with long-term health conditions and disabilities, visible and invisible, which makes being required to do tasks such as strip beds and take bin bags out on the day of departure physically taxing and difficult. I think there's a lot of difference between expecting that guests leave a place in a decent general standard of cleanliness and requiring them to do physically taxing household tasks at the end of their stay.
Sometimes I think that hosts and holiday-let companies can only imagine their guests being exactly like themselves, with all of the same physical capabilities, and don't consider the possibility of anyone staying at their property who has less physical health than themselves.
I remember going to stay in one holiday let; it wasn't an Airbnb, it was a property run through one of the big, well-known UK holiday let portals. We'd stayed in their properties for years, but we went to one just after Covid, and they'd changed the usual rules, so they were requesting guests strip the bedding and take the bins out at the end of the stay. Because we'd stayed with them many times before, I hadn't checked the terms beforehand, not imagining they would have changed. We had two young children at the time, so we had three beds to strip, with a required departure time of 9 am - a bit of a push with young children to organise and a long-term health condition that causes chronic fatigue and joint subluxations on exertion. I ended up doing the tasks to get us out on time but was in considerable pain afterwards and needed several days to recover.
At home, I would never strip three beds on one day. I need to pace myself and rest after each one. Like most people with long-term health conditions and disabilities, I stagger household tasks across a week, and I buy items to make these tasks easier for me – a duvet cover with a zip all around, or a coverless duvet, a dustpan and brush with a long handle, bins positioned near our door so I don't have to carry them far.
If you're at home, and you have physical limitations, you have almost certainly put lots of small accommodations like these in place to make your life easier and minimise your pain and fatigue. If you're staying in a holiday rental, you can't do this; you have to work with what they have, which probably won't have been purchased with accessibility in mind.
I don't want to have to stay in a hotel – we love the peace and relaxation of self-catering, and we want to go on holiday to little out-of-the-way places. Why should people with physical limitations be restricted to hotels? My health condition includes food-related symptom flare-ups, which means that self-catering is much better for me. I will always be a considerate guest and leave a property clean, wash up the dishes, etc., but I resent being asked to do multiple physically exerting tasks at the end of a stay when I am paying a considerable sum of money for the holiday, and I know that there will be a cleaner coming in at the end who is much more physically able than me.
I think it was maybe different in the early days of Airbnb, when the concept was that you had a cheap stay in someone's home. It seems entirely reasonable to expect that, to balance out a cheap homestay, you do more in the way of household tasks – much like the old days of the YHA, where you were expected to do a task under the direction of the warden each night to help contribute and "pay" towards your cheap stay at the hostel. But Airbnb stopped operating under that model years ago and has become just like any other holiday-let operator or rental portal, with prices set to match.
