This wouldn't work in my situation, where I host long-term guests. I cannot imagine not offering them kitchen access. These people are staying for months, not days, and are not tourists/coming for work meetings. They are living here and working from home and they need to eat. It would not only be totally uneconomical for them to go out for every meal, snack and drink and, even if they had the time/money to do so, it's hardly fair to ask them to repeatedly expose themselves when we are all being told to stay at home as much as possible.
There are only three solutions as far as I can see:
1. Stop hosting on Airbnb.
2. Have designated times for kitchen use/meals so that we don't cross paths.
However, the latter doesn't address the issues of sanitising shared spaces. Do I have to go in and disinfect every surface after every time they or I enter the kitchen? Do I have to do this in shared bathrooms, e.g. each time someone goes to the toilet? There is no point suggesting that I leave out disinfectant and anti-viral wipes so that guests can do this themselves, because I started doing that at the beginning of the pandemic and nobody uses them.
As for guests wearing masks in all communal spaces. It's never going to happen. Not with long-termers anyway. They see this as their home and the only place they can finally take off their masks. Anyway, they can't wear masks while they eat or in the shower or while they brush their teeth!!
This policy is clearly a PR stunt or 'hygiene theatre' as highlighted in the Wired article on another post here. It is simply impossible I imagine for the vast majority of homeshare hosts.
