I joined Airbnb as a host last November. Currently I'm hosting the most clean and tidy guests I have ever had. The two guests are a mother and her teenage daughter from China.
Before they checked in, I sent them "Things to know," "House Rules and House Etiquette," and "Frequently Asked Questions," and reminded them to read all of them carefully when it was close to their check-in date. On the day they checked in, I gave them an on-site orientation. They listened carefully and swore to me that they would follow all the rules.
Previous female guests left so much long fallen hair everywhere especially after brushing or combing their hair, on the bathroom floor, bedroom floor, on and inside of the duvet, on the pillows, on the area rugs... Trust me, your washing machine and tumbler dryer won't get rid of all of them; technically I would need to examine and remove all the hair manually.
But these two guests, both with long hair, leave not one single hair in the bathroom or in common areas. I hold my newly bought V8 Dyson vaccum cleaner and examine every corner in my house that they have been to and I find not one single hair. Yesterday morning, I saw a cluster of long fallen hair in the toilet bowl and I flushed them. Apparently, they had cleaned the floor and collected their own fallen hair and thrown them into the toilet bowl.
I also check my kitchen after they have used it. It is spotless.
They are the most clean and tidy guests I have ever had. Thorough communication has played an instrumental role in this. I will buy them a dessert over the weekend.
