It's a lovely apartment, silent and sunny and the location is great. You find everything you need close by. There's a nice place that offers hand craft beer and good food just downstairs (Hopificio), there are also nice restaurants like Pizzeria Cocco and Osteria 22.
The metro Furio Camillo is just 300m from the apartment as well as the entrance to the huge park of the Appia Antica. We enjoyed exploring the city and park by bicycle. It took us 20 minutes to reach the Colosseum.
Nicola was full of great advices , "Cocco" was one of those :-). This is the real Rome experience out of the beaten track! Highly reccomended.
