Marta's unit was spotlessly clean, and she met us in person to let us into the unit. Trastevere is a charming area full of cafes and restaurants. One can walk in about half an hour to many sites such as Piazza Navona, Colosseum, Vatican, St. Peter's Square, etc. The unit is on a side-street so it is pretty quiet even though the night life of the area is lively. We enjoyed our stay!
