We have rented many times from Air Bnb, VRBO, etc. Our selection of a property always starts with the location, so I would that a desirable location is important. Second screening parameter is the number of people the property can accommodate, and then price. Property that is well presented with nice photos and good descriptions of the area, things to do etc. definitely catches my attention. I am willing to pay a bit more for a property where someone has gone to the trouble to paint a beautiful verbal and photographic picture of what my vacation will be like.
