Four of us stayed at Maria's apartment with with two teen age children. There was more than ample space. The apartment is amazing and has great amenities. There is a new mall within a 3 minute walking distance that has groceries, shopping and restaurants. There are also local establishments to eat at right around the corner. You are less than a five minute walk to the metro station that connects you to all of Rome.
Maria is a wonderful host and so helpful with questions.
This is a fantastic option for anyone wanting to experience Rome.
