@Chris13135 sometimes guests book a group with one ID. I have noticed this with poor reviews. If its a couple, they may book with the account of the person who has the best feedback. I had that happen recently with a guest who brought a boyfriend who smoked a lot of pot in my house. Her profile showed one positive review. His showed several negative for smoking and not following house rules, as I figured out after the stay doing some digging.
I would just message and say:
"Thank you so much for your interest in my space. Please verify all the guests who will be staying and add them to your request by having them register with Airbnb. I will be happy to review the request once you have a finalized guest count. Thanks again and have a great day!"
Two weeks is a LONG time to have a poor guest experience. As a new host, concentrate on building up your positive reviews with short stays rather than trying to attract longer stays at first. Lots of poor guests target good hosts and it can really tank your rating.
