Emilio was an excellent host. He was incredibly responsive and helpful. In terms of the apartment, it was very comfortable and in a very good location. It is an easy walk to the Metro A line which will take you to the popular sites (like the Vatican or Fontana di Trevi) or an easy transfer to the B line for other sites like the Colesseum. The neighborhood was safe and private. There is an amazing dessert spot within walking distance called Pompi. Go there.
