We never met Rosanna but she is very fast to communicate! Their home is spacious and nice. Had a little problem during our stay but she came right away to try and resolve it. They give you a lot of maps and tourist information for Rome which was very helpful! In a safe building, less than 10 minutes from the train station and 10 minutes to the colosseum. We still walked to everything except for the Vatican which is easy to get to by bus from the station. Fernando the door man showed us in the apartment and he was a great help! I'd recommend staying here.
