I do some stuff here and there. I think adding a little to the space makes most people feel at home. If it is overbearing it may deter some guests from having a great time, as opposed to just a decent time if they don’t celebrate. Some lights and a few winter wonderland-ish decorations would be fine in my opinion.
@Andrea6194 To me the holidays mean Hanukkah. More so this year than ever. Not that I would decorate my airbnb for it. I also love and celebrate new year in a traditional for my birth country way and my personal home is heavily decorated for it during the season
