Hi @Sylvia664! Here is where you can elaborate on @Mike-And-Jane0's comment:

As to your listing - it's really lovely. Some notes:
The title says Sunshine Skyway AND downtown - in my experience the two are not close to one another, so which is it?
I don't think your nightly fee is high enough although I notice you charge a little more after a certain number of guests. Keep an eye on your rates because lower rates attract lower quality guests.
Your pictures are really good except the one with the toilet seat up. That just drives me crazy. No one wants to see that.
$250 is not enough of a "security deposit" - it should be $500. And just fyi, there isn't really a security deposit. Airbnb doesn't hold that money back at all, and if you have a condition that requires you to ask the guest for some or all of that deposit, they can refuse. That's why your rates should be high enough to cover unexpected damage.
You should have a minimum night stay of two or three nights. One-night stays can attract partiers and in general they're not worth it.
As a new host you might want to consider blocking a day before and after each reservation, just to make sure you have time to inspect the property between guests and get it cleaned. If you do discover damage, you have to reach out to both the guest and Airbnb before the next guest checks in, and same-day bookings rarely allow that.
All of this might be moot after you read St. Pete's short-term rental regulations...
