Disney Bay lake Tower listing for Dec 13 through Sept 14

There is a listing for Bay lake tower in Disney that spans over several months. Is this a legitimate listing? It is different from other listings because most listings are for specific weeks. Is it safe to rent from this person and what can I do to protect myself? It seems too good to be true!

Thanks!

If it's a floating week it can span several months.

Thank you. Im new to this and it just seems too good to be true.
