We had a great time during our stay at Stephano's place. He was very helpful (the cab driver dropped us off 2 blocks from his place. He walked over with his friend and helped us with ALL our luggage), very knowledgeable about the area and attractions (all the places we ate in came from his recommendations and each one of them were outstanding restaurants) and very thoughtful (he had kept a baby cot and a high chair for our 2 yr old before we checked in). As mentioned, the place is in a quiet, very Roman kind of neighborhood. But at the same time, only a few minutes walk to the Colosseum and a lot of bars and restaurants.
If I'm in Rome again, I'll definitely stay here.
