Use powerpoint. I find this much easier (than Word), as you can switch between slides. For example, one slide has the names of the rooms. The next slide with the stick figure doesn’t, so students have to remember the names.
Text wrapping is also important because it’s much easier to change the size and move it around properly. With text wrapping as Through any background automatically cuts out so you don’t need to do any further editing. And you may want to select Through as the text wrapping option for the house/image you choose as well. This makes it easier to resize.
