Humberto was a great host for our family of 5 - Rome being our first stop in Europe, he made sure we were completely acquainted with the city, gave us a cell-phone preloaded with data and with suggestions of places to visit and eat etc., and was always available before and during our stay (even after our stay!) to resolve any queries we had. The house is spacious and fully equipped, very close to the metro station, all groceries and requirements near by.
I would stay at Humberto's again, in a heartbeat.
