We LOVED our stay at Lavinia's appartment. La "casa de la luz" really deserves its name. It is full of light all day long, the terrace was just lovely on these first spring days, and the street is quiet but still relatively close to the center, and to the heart of Trastevere.
Lavinia was very helpful with everything and responded quickly to any request we had. I really appreciated her flexibility with our arrival and departure times, too. We definitely would love to come back.
