Rental for my Snowbird parents

My parents and uncle and aunt like to spend the month of February in Pompano Beach/Ft Lauderdale/Hollywood (must be nice!) They've really struggled with finding good rentals on AirBnB. The rentals are hit and miss, and since they live far they can't really check them out beforehand. Anybody have ideas of a good place to find month-long rentals for snowbirds that's reputable?
