I sadly had to cancel my trip, after my father-in-law passed away the very evening I was supposed to travel.
Ralf had been extremely helpful, efficient and communicative in the run-up to my trip.
Ralf was also very kind when I messaged him to explain that I wasn't coming.
The AirBnB review system didn't have an option for me to say what had happened, but I wanted to make sure Ralf was recognised for having done a good job in the run-up to my stay, for and being so kind to me when I had to cancel.
Hence the 5* rating even though I didn't actually make it to Ralf's place.
