Francesca's apartment is beautiful - even better than the pictures. Location is good, walking distance to the Colosseum and 2 metro stops from Roma Termini Station (you can catch the express train to/from the airport from there). It's a bit more of a walk to other sites such as the Vatican or Piazza di Spagna which are further north, but it's a beautiful walk and we also caught a bus a couple of minutes from the apartment that took us to other areas quickly. Francesca was really helpful and I'd definitely recommend her apartment for anyone spending time in Rome.
