I loved this room. It's the first time I had a room and did not have to share a bathroom with my host. It was a great feeling, the room was well equipped and could have passed for a hotel room.
Donatella stayed up to received me when I arrived later than the ETA I had provided to her. Even though she doesn't understand English, or I Italian, we were able to communicate and I understood her and her house rules perfectly.
Her place is less than 5 minutes from the metro and just a few minutes walk to the Vatican Museum/Vatican City which was great.
This wonderful place with its wonderful host deserve 5 stars and I recommend it for anyone going to Rome.
