Giulia was amazing. I stayed at her apartment with my sister. We had a private room and shared a bathroom with her and her boyfriend. Her place was remodeled and sparkling clean. It’s located just a few blocks from the train station and it’s very close to the center. San Giovani is about 5 minutes walk and the colosseum is about 18 minutes walk, and from the colosseum you can walk to everything else (except the Vatican which you can take the train to). We barely spent anything on transportation! Guilia and her boyfriend were very nice to us and they answered all of our questions about the city. Guilia even checked on us if we stayed out late! On our first night her boyfriend walked us to the restaurants area near by. She cleaned the room everyday after we left and let us leave our luggage with the the last day. I strongly recommend her!
