@Tom888 I also don't have anything personal in the guest space- their bedroom or bathroom. It just is set up like a little hotel room. The decor isn't impersonal, art-by-the-pound- there are framed artworks done by friends and family, quirky little decorations (but I actually dislike knick-knacks, so almost none of that stuff- just more to clean or break) but no personal photos. Of course, in a shared home situation, where the guest has use of common spaces, there will be whatever the host normally lives with.
