@Женя0 your reviews are all really nice - BUT your cleaning star is lower??? So what happened? This is before the guest you are talking about today -
so I wouldn't worry about her - just be nice, you did what you could - don't be hostage to the reviews and fear of that. People are gonna be all sizes, shapes and personalities. Angry would be the worse. She could be one of those aiming to milk the system for a refund. I would send messaging through the Airbnb app about any conversations....and if she is angry, I would say, sounds like you are angry and I am sorry, etc. quoting what she actually says, if it is ugly stuff, "quote" it so Airbnb sees she is not a nice guests.. Just keep a trail of anything that is said between you two. Remember if she is awful you can report her, give her very low stars and move on to the next wonderful guests!!!
just note that the cleaning star is probably the most important! All places must be clean. Maybe try to figure out what you can do to make sure that everything is sparkling clean. happy hosting
