I stayed at Gianmarco's place for 10 days with two friends (from Canada and Israel). The location is great: it is close to a metro station, with many attractions being in a walking distance. My communication with Gianmarco was great, he was responding very quickly to all my messages. He also gave us a detailed description of what is available in the area. If I ever come back to Rome, I would love to stay in that same place and I highly recommend it to Rome's visitors.
