The landlord on purpose wait to reply after the refund deadline. We lost all our money, almost 1700 euro. Even with proof, Airbnb nor the landlord will help you. I called with the landlord and he wouldn't reschedule because "covid is killing his company" while his company profit gained +700% in one year (https://www.companyweb.be/bedrijf/gmfb/bv-bvba/687533426). Maybe the host is friendly but the landlord only cares about profit. Go to a place where people actually care about you and don't use covid as a scapecoat.
