I ended up getting COVID a week before my trip and asked if I could cancel my reservation. He said it's OK and I could just come anyways. I'd hate to be other guests in the house if I had actually decided to make the trip while I had COVID.
He offered a partial refund (less than half of what I paid) because he was able to rent the room to someone else so that deserves more than 1 star. The kicker though is that I just received the check in the mail and it's less than what we agreed upon.
Don't book a room that doesn't allow for refunds/cancellations especially while we're still in a pandemic. Lesson learned.
