My favorite place to stay is a little 4-bedroom B&B in Berlin called mittendrin. I've stayed 40 nights over the last 4 years. Part of the charm is staying in an early 20th century building that has maintained its bones/internal character (despite an updated facade); much of the charm, though, is the gracious owner and hostess Sabine. I had reserved a room for April 30 to May 6 via e-mail earlier in the year.
I wrote Sabine to apologetically cancel my reservation and told her I would still like to pay for the room, emulating a good German who honors his agreement, even if unable to keep it. I expressed concern for her and her business. I ventured an informal "Liebe Grüße" ending, instead of the more business-appropriate "Mit freundlichen Grüßen" ending.
Part of her response (via Google Translate):
My dear Dave, thank you so much for your warm words. Yes, mittendrin
is closed until further notice. Unfortunately, most are not good
Germans and do not voluntarily pay cancellation fees. So it touched me
very much that you want to pay. But please dear Dave, you do not have
to pay for this, this is force majeure and I do not want to charge any
cancellation fees. But a thousand thanks for your offer. I do my best
to get through the middle of the Corona crisis and then we have a
party with red bull and champagne, if we can see each other again in
spring next year, that would be great.
A sweet, sweet lady (who remembers my bad Red Bull habit!).
