I would definitely recommend Elisa's apartment. It's a lovely and clean little place with everything you need to rest up after a day out and about in Rome. It's really easy to get to from the center of Rome with the bus and Metro stops just round the corner and Elisa was really helpful in giving us several options of how to get to the apartment from the airport we flew into. We didn't meet in person but communication with Elisa was always pleasant, quick and easy. Pigneto itself is a great neighbourhood away from the tourist center and has some great bars and restaurants, Necci dal 1924 - great for breakfast and open in the evenings and just down the road from the metro, Beliveat and Va Do also just down the road, and our favourite and a must if you like Japanese food - Waraku which is a 5min walk from Teano metro.
