Looking for a month or 2-month rental on St. Thomas

I'm looking on VRBO and a few other rental sites, but someone mentioned on TripAdvisor that we should try and rent directly through an owner. That worries me, but does anyone know of someone who rents? Just my husband and me. Must have a fully equipped kitchen. Prefer air conditioning, screens in windows/doors, washer and dryer and king-sized bed. Working internet is a must. Wouldn't mind any other advice as to where to stay in St. Thomas you want to give too. Thanks in advance!
