Roberta is an excellent host, making sure that we were very comfortable and going out of her way to make our restaurant reservation. The restaurants she recommended were local, serving good food at reasonable prices. She was there on our arrival and very relaxed about our departure time.
The apartment is a studio flat on the ground floor of a larger block that is partly commercial and partly residential. It is well equipped and secure, though with limited natural daylight.
Very close to the Vatican and metro.
