The apartment is lovely and has a double room, a single room and a double sofa bed in the living room. The vatican is within walking distance but for most other attractions you can take a bus from the bottom of the street which gets you to the centre in about 20 minutes. There are lots of places nearby to get groceries and a good restaurant at the bottom of the road. The immediate area around the flat is a bit noisy and there are overflowing rubbish bins and trash in the street but i think that is typical of Rome. We felt very safe and would recommend staying here.
