"A floor plan can go a long way toward helping prospective renters visualize what it would be like to stay at your property. The descriptive copy in your online listing might say, “Our ocean-front condo has a living room, dining room, kitchen, and two bedrooms and bathrooms,” but a floor plan—particularly one that includes major pieces of furniture—makes it “real.”
You can include a floor plan as one of the three or four image files that are part of a standard online vacation rental listing. Or you can pay a bit extra to add extra images to your listing and use your floor plan for one or more of them. There is no question about it: Including a floor plan will make your listing stand out from the competition and probably result in more bookings."
