Elena's apartment was very nice and clean, the neighborhood is quiet. The bus station is located nearby, you can get to the city centre in 25 min. It is also not far from train station, so you can easily get to Termini. We saw the construction of a new metro station in the area, so I suppose it will make transport access even better in the future.
I can say that it's a great place to stay for a few days in Rome if you don't mind using public transport. We were very satisfied with the looks of the apartment, too. It shows good taste.
Elena is a very nice host, she helped us with everything we needed. Moreover, she recommended us some nice places to visit in the neighborhood and a cafe with perfect cappuccino.
