@Barbara3817 . Great comment and I agree with everything you mentioned.
As a host we have double the crockery for maximum capacity as a minimum. Even in our studio listing (max 2) we have 4 large mugs and 4 tea cups. Same for cutlery (often triple if you include steak knives) but always with extra tea spoons.
We find even the weekend stays appreciate home away from home facilities so thats tea towels/dishtowels, paper towels, cleaning up supplies. I've even had a guest at another listing mention after a stay that rubber gloves would have been handy so we added those (even though there was a dishwasher).
With bedding, extra blankets and throws because even Summer can turn cold suddenly.
Re steps, use the accessibility filter to choose or you can always contact the listing host with an enquiry about railings.
Although we are all different hosts I think you will find the higher rated ones are often more generous with their provisioning and thats often reflected in the ratings as well as review comments.
All the best.
