I spent one week with my husband and our three children in Marco's apartment. It was very easy to communicate with Marco.
The apartment was exactly as described, very clean and spacious, even for a family. It is closed to Cornelia subway station so that we could very easily reach the main touristic and attractive areas of Roma. People in the shops and restaurants around the apartment were very kind, especially with children.
We had a very nice time in Roma and we recommend this address.
