Think Brooklyn or Philly brownstone with lots of the old lovely touches, that have been modernized over the years here-and-there. There are steps, which my 80-year-old mom handled, but if she were 85....maybe not. The front steps go to the front door, then there is a staircase to the main floor (really the second floor) and then twisting stairs to the top floor (the third floor). If your mom snores, perfect, as she can sleep on the main floor bed and has her own bathroom while you sleep on the upper floor with your own bathroom. Snore-proof. The third floor has a large space for kids to play but also has a spacious desk where you can get your work done.
