We've had a wonderfull time at Dario's house. It was exactly as the advertisment said, very confortable. It was located near Termini Station, so we could go walking to zones like Forum, Collyseum or Santa Maria Maggiore. And at the station there were planty of buses and a subway station, so it was very well connected.
At the neighborhood we found interesting night live, delicious and very tipical restaurants and, for us the more important, it was not a touristic area, so prices were'nt high and you could get envolved by the roman ambience.
Dario was helpfull and the house was well conditionated, so we recomend it, specially for ypung people.
