We spent 6 days in Rome. We enjoyed our stay in the apartment. Maurizio's sister gave us some informations (transports to the town center/the apartment, restaurants, supermarkets...) when we arrived. There are lots of restaurants in the neighborhood, which is lively especially in the weekend.
However, we thought that the apartment was a little too far from Termini station (20 minutes). Moreover, even if the apartment was cosy and calm, we found that there wasn't enough equipment in the kitchenette (kitchen sink, pans adapted to the hotplate..).
