I don’t it depends on what sorts of people are attracted to stay in your area @Michaela273 .
it could be your local post Covid market is those coming to work? When you did your market research on those with similar properties locally what sort of guests are they attracting by their reviews.
Another scenario is you have set your prices/monthly discount too low and are attracting bargain hunters.
what sort of guests did you want to target when you set up your listing?
Personally as a new host I would only accept shorter stays , both so you can get use to STR and so you can get more reviews. You can set your listing so you have a max stay of a week or two.
You can also set your listing so you only accept guests with a. Verified ID b. Have a profile pic c. Have at least one review.
