The apartment is really nicely situated, just 5min outside the Adrian walls. The Metro station is very near, an invaluable asset in Rome (avoid the buses when you can). There is a lively neighbourhood around, with lot's of possibilities to dine. One can also directly walk to the Colosseo (20min), passing the majestic Basilica San Giovanni. Cristina is a lovely host, I had a very nice stay at her place, highly recommended!
