@Linda354 Correct. This is just a discussion forum for hosts and guests. Good place to get feedback and support or ask questions if you have an issue or just want to chat or vent (also great for being alerted to site format changes or glitches- it's useful to know that tons of other hosts are experiencing a certain glitch, so you don't think it's just a problem on your account), but Airbnb doesn't read or respond to what is posted here. The forum moderators will sometimes try to escalate an issue someone is having with CS, if the host or guest hasn't been getting any response to their problem, but that's about it.
Occasionally requirements do get changed with enough feedback directly to Airbnb- a few years ago Airbnb made providing linens and towels mandatory, which most hosts wouldn't find odd, but there was a huge outcry from hosts with vacation rentals in places where it is traditional for guests to bring their own- this seemed to be beach or lakeside cabins on the east coast of the US and some places in Europe, primarily. These were remote places that the hosts lived far from, and providing clean bedding and towels for places that might get booked for a dozen people for a couple of weeks or more just wasn't possible or would be prohibitively expensive. Plus, like I said, guests coming to those places were accustomed to bringing their own linens- they were places you would have to drive to, anyway. So it took awhile, but Airbnb did backtrack on making that a requirement, although it is "strongly encouraged".
Hopefully more hosts will let Airbnb know that the washing machine requirement for long-term stays should be nixed.
I think there was another thread here started a day or two ago about the long stay/washer requirement. Maybe type some key words in the search engine and you can find it.
