My wife, myself and our 6 year old son. My wife will homeschool so the distance from schools is not important. We would ideally want a two bedroom but we could make a one bedroom with a pullout bed on the couch work. You know 6 year old boys; they are happy on the floor most of the time.
We would definitely want a kitchen so that we could eat at home. Other than that, we're easy to please.
