Ivan was great. He helped us find the place and took care of parking space for our car. He introduced us to the Pigneto area and even found us a local pizzeria to try some great pizza. Ivan's place is located in main "hipster" area in Pigneto, you can almost proclaim it you terrace and go sit on benches and enjoy the evening flow of people there.
Ivan was also very helpfull with explainig the bus routes and ways to get to the center of Rome where all art/historical attractions are.
Definitely recommended .. ;)
