Porta Furba area is really handy for walking to the soul do. Arco di Travertino and Colli Albani are also pretty close, all are relatively cheap for taxi fares to the do and any of them are only a few stops on the metro for central Rome sight seeing. Restaurants, bars, cafes etc are also cheaper than central Rome. Accommodation can be found on AirBnB, Booking.com and many other accommodation sites.
