No, Michael, this site exists because Airbnb doesn’t understand basic human decency. And the fact they have their dogs like you running around this site, barking incorrect facts and hate, just further proves it 🙂

Good to read that you admit being a professional cheapskate. It’s mainly due to folks like you that this website exists……

I wouldn’t know how to deal with this to be honest. I would try to message the host again to explain the timeline you are on due to your visa application. That you understand this new law is difficult for them too but that you simply can not wait to hear yes/no 10 days before your trip since that is too short to arrange your visa. You can also say that I will cancel regardless, and that it’s better for them to keep the listing for those days online so local guests can book it, because they will lose money if you cancel (if you have to, cancel absolutely at the last minute if the host is not willing to accept your cancellation now).
Another strategy: explain how difficult your position is to the host, the host may agree to cancel. If not, go and stay at this place (if possible, even if you might get your visa on another address) and ruin this host’s ‘game’. Complain to airbnb about mould, smell, pest infestation, anything that a ‘guest from hell’ can get away with to get a full refund for their stay, maybe even a free stay (I think I’ve read about people complaining about things halfway into their stay and get all their money back). This host is being insensitive towards your situation, so when they don’t want to be decent, ruin their business when you are forced to keep the reservation.
