Our house is a 5 level split so 7 steps at every level. Our bedroom is one level up, three bedrooms and a bath another level up. Off the main floor are 7 steps to the lower level and then 7 more to the basement. So no matter where I go in this house I do the steps. I like it because I think it keeps us young and limber to have to do the steps no matter how slowly. I'm in the basement and I love it that all my mess is confined and I never have to clean up between projects unless I can't take it any more. Do what is comfortable for you and put the guests wherever you have left. We have 5 bedrooms and usually one kid comes over at a time.
