Anyone w/ feedback on Hapi Florida Vacation management company?

[Penmac]

We are spending a week at Disney in August. We originally booked at Sheraton Vistana Lake Buena Vista but now have additional family members thinking of joining us. We had free cancellation so I am starting from scratch and trying to decide what to do. I generally like to stick with timeshare resorts, but a home rental may be a better fit for our needs. I received a decent quote through Windsor Hills Official rentals for a 4 bedroom pool home. It looks ok, but I am unfamiliar with the management company which makes me a little nervous. The owner lives overseas. Anyone with feedback on this company? I am thinking since it's a quote through the official rental page it should be legit, but I like to do extra vetting, either way.
