Elisa's apartment is beautiful and perfectly located. It is really close to the Vatican and the area is really lovely, with nearby grocery stores, shops and restaurants (some of the best gelaterias are in the area). The metro is close, but we didn't even need it, as the apartment was close enough for us to walk to the major attractions and areas that we wanted to visit - like the Piazza di Spagna and Trevi Fountain (the walk takes 25 - 30 minutes and is filled with beautiful scenery, and is a wonderful way of exploring Rome).
Elisa's responses to my questions were really quick, and she very kindly organised an early and check-in for me. The flat was clean, fitted with all the required amenities and is just like it looks in pictures. I would highly recommend her apartment
