Underrated - garbage disposal. I went from having one to not having one, and while it probably wouldn't affect me renting a place or not if I liked everything else, it is something to consider.

I'm a "big common space" and "laundry on-site" person as well. But if you have laundry on-site, you should have one washer/dryer per apartment if at all possible. Otherwise, it's not that convenient.
