Who knew a slice of Spain was tucked away in this Rittenhouse mansion? The front door opens to the first floor's massive entertaining space: It's an indoor Spanish courtyard with 16-foot-high ceilings, a Mercer-tiled floor and fountain, a fireplace, and a stained glass window. The stone staircase leads you up three stories to the home's four bedrooms and 3.5 baths. From the second-floor living area and dining room there's access to a private, cedar wood roof deck. Street parking isn't an issue, either—the 5,400-square-foot space includes a gated parking area fit for three cars. The asking price of this townhouse on 321 S. 17th St. is $1,499,000.
