I and my family enjoyed a lot to stay at Roberto's place. Rome is composed of old buildings, internally renovated with modern appliances and equipments. Roberto offers a renovated home, with new furniture, heating system, and new bathrooms. It is located in the heart of Rome, walking distance to the Fontana di Trevi , the Scalina Spagna (Spanish Steps), and (if you are a walker) the Colosseum. It is close to the Spagna Metro station, so you can get to Vatican City in about 15 minutes. The only important observation is that the place is located inside the ZTL (traffic restriction zone), so you cannot access the place with a rented car, you need to use taxi or public transportation to get in and out, what was not problem with a proper planning and there are taxi's point in Piazza di Spagna
This is a great place to stay in Rome, I strongly recommend and I would stay again.
