@Ute42 yes, I believe @Sarah977 is right. It's been mentioned many times that the fund is for Superhosts and also Experience hosts.
I am not sure if the goalposts keep shifting regarding the Superhosts, or it's simply that they keep releasing a tiny (minimum) amount of further detail on this as so many hosts are begging for more information. I have given up, quite frankly.
Firstly, I thought I didn't qualify because I had three rooms listed, albeit in my own home and only property, which I thought unfair. Then @Sarah977 alerted me to the update where it said that hosts with more than two listings in their own homes did qualify after all. Now, they say the focus is on those who have been Superhosts for four or more years (for me it's around two) which I have less truck with as it seems a fairer way to narrow down the selection. It's all still a bit cloak and dagger though.
What do they mean by the greatest loss of income? Is that the percentage of income lost or the actual amount, because $1,000 in a wealthy country is very different to $1,000 in a developing country?
