Homestead laws here in Florida are weird to say the least. How is she “commenting on your reviews”? Certainly not on AirBnb, where I can read reviews but not comment on them.
How did she “contact you”? By phone? Email? An official letter on county stationary? If it were me, I would contact my lawyer to look at the homestead laws in detail. I would personally ignore this woman until a Process Server shows up with a legal demand for your records. You can, of course print out your AirBnb rental dates for them, but I would redact the names of the guests.
