Without a doubt the worst experience I've ever had on AirBnB. My advice is to find another host. My decision to trust Apostolos with my booking was a mistake that has cost me over 500€.
The booking, made in March 2020, was for October 2020. When it became clear that the Coronavirus situation meant that it wasn't safe for the booking to go ahead, Apostolos was kind enough to let me move the booking to April at short notice, for which I was grateful.
In February it became clear that the April booking would not be possible given UK or German Covid regulations. I requested to re-book for August. Apostolos refused. I messaged him asking him to reconsider or cancel the booking and suggesting we come to an agreement on a refund to cover some of his costs, but he failed to respond. German Coronavirus regulations meant that the trip would not be lawful, and Apostolos was meant to have cancelled the booking on his own initiative as per German regulations, but he failed to do so. AirBnB support requested he provide a full or partial refund, but Apostolos refused citing financial hardship, and insisted the booking go ahead or that I cancel, with AirBnB upholding the strict cancellation policy.
When I didn't cancel, and continued to constructively try and come to a fair agreement and outcome with Apostolos, he ghosted me, and has not responded to any of my messages in 10 days, despite me being meant to stay in his place (and being charged handsomely for it).
This is particularly disappointing, as I had stayed with Apostolos twice before and trusted him to behave reasonably, indeed I liked the quirky room and was looking forward to staying again when it became possible and legal. In hindsight, trusting Apostolos to behave reasonably like this was a mistake.
I am still exploring other avenues to recoup my money and time lost, but would caution all guests to avoid booking at this property or with this host.
