A good idea. BUT, you also need to record the location location and direction you're facing. Bring a whiteboard and write stuff like "Downstairs powder room, facing front" and put that in the frame. Without walls and fixtures, it can be really hard to tell what you're looking at -- that's especially true if, for example, you're taking a photo of the ceiling.

AS an added benefit, if your handwriting is neat enough, then Google photos will recognize it and then you can just do a search for "powder room" and you'll get all the photos from there.
