Dario's place is perfectly located. Close by the train station (Roma Tiburtina) that could take you anywhere you'd like. Also, there are a couple of places to eat and a very convenient supermarket just steps from the building.
The place is clean and big enough to spend a few days in beautiful Rome. Beats a hotel room every day!
Dario was very responsive and helpful every time we needed something.
Definitely, this is the place that you want to stay.
Grazie Dario!
