We stayed at Marco's place with our 17 month old son. Marco was really helpful to set everything to our son (babycot, highchair, babybath, plates and cuttlery). Communication was easy, Marco reacted quickly, and was a super host. Neighborhood is quiet, and appartment is just few minutues from Colosseo and tram/bus/metro, so you can reach attractions easily. Our favourite escape was Giardino degli aranci which is just 15 minutes from appartment with tram/bus. I highly reccomend this place for your stay at Rome.
