Flavia's place was indeed the perfect location. I walked to the Coliseum(15min), the Trevi Fountain(7min) and although I took a taxi to the Vatican it was very much so walkable I was just tired(7euros for taxi) lol... Everything you need is at your fingertips.. I enjoyed the coffee shop around the corner... the pizza was amazing near the Trevi fountain ... there were plenty of shops around ... upon arrival Flavia's mother greeted me and was very informative about the city. I would definitely recommend this place. I was traveling alone and it was the perfect. I felt safe and although I got lost a few times venturing off there were landmarks all around that helped me get back to Flavia's comfortable place. You will not be disappointed:)
