We stayed in Elisa's appartment when we passed through Rome on our Honey Moon and it was absolutely fantastic! The appartment itself is very clean, very well equipped and situated in the very fun and hip area of Pigneto. We enjoyed a meal at Necci (up the road) which was delicious as were the pizzas in Margari (slightly further up the road). Getting into central Rome is either a 10 minute tram ride or a 25 minute walk. My top tip for Rome is get a Roma pass to avoid queues at various museums and Historical sites, catch a train to Ostia Antica (ancient Roman village near the sea) and spend a day on the lakes near Bracciano (an hours train journey).
