A professional - such as myself - will take photos that show only two walls, thus emphasizing the openness of a room (first image below). Shooting this way minimizes converging lines, making the room look as big as possible.

The "SHOE BOX" effect, is created when a photograph includes a third wall, or part of a third wall in the composition. The lines between the floor, walls and ceiling converge as they recess into the room, thus making any room look much smaller than it is. A photograph that includes a third wall is a bad photograph, does not show your listing in the best possible way and should not be accepted. (second image below).

I "always" only shoot two walls. If there is something on the third or fourth wall worth showing, then I simply take another photo from another angle featuring that highlight. My rates are structured to accommodate what needs to be done to make your listing look great.
