I believe airbnb has to ask its hosts to put their apartment floor plan showing what is the size of the rooms, bath, shower, etc. Also hosts should put pictures of the building doors , building view and some pictures form the street or alleys their building are built at. Note: the outside pictures should be taken exactly from the location of the building not more than few feet far from the property. In this way people who want to rent it will understand what they are going to get.
