Cate's apartment is in a fantastic location. I have just spent 3 nights with a friend and we walked everywhere, to all the major sites such as the Vatican, Coliseum, Trevi fountain and the Spanish steps. The apartment is located about 3 minutes walk from Piazza Navona. The apartment is easy to find - if you travel from the train station by bus, you just need to look for a little street between the Pan Local supermarket and the Farmicia. Cate met us at the apartment and was very informative about the area, where to eat etc. I will be recommending this place to others.
