We had a wonderful stay at Cristina's apartment! The location is so close to a metro station that we used frequently to get to main attractions. It is also short 10 minute walk to the Vatican which makes it easy to get to for the early morning tours and it is a few blocks away from Mercato Trionfale. I always felt safe walking in the area at night from the metro to the apartment. The apartment was clean and the living room with extra sleeping arrangements has a door so it can act like another bedroom. It was easy to communicate with Cristina and she was very responsive--she provided documents with a lot of helpful information for your stay and travel tips. She accommodated an early check-in for us and coordinated taxi rides to the airport that were flawless.
