I would like to see a prominent place for the Square Footage. For example: If one place hosts four with one bedroom and a full size couples bed and room to barely walk around, and another is twice as large and hosts four and the bedroom has a California King bed, and there is plenty of room to move, this is a big difference. This is an important factor in choosing one's accomodations. Some people don't mind a small turn around place if out all the time and just want a place to sleep. Someone else may want more room to move.
When a listing says One bedroom, many people never look at the details to see what size the beds are and have no idea how crowded or comfortable they would be.
