We enjoyed our stay in this apartment, the conversation with the host was always fast and effective. We found the apartment exactly as described. There was space for 4 people - one sleeping room with doublebed and the main room with sleeping sofa. (The doublebed is more comfortable ;-)
You should know, there is some noise in the morning, but you will find this Vespa and little trucks all over Rome, that's maybe part of the Charme. We recommend!
