Donatella's apartment was lovely!!!! Has everything you need to make breakfast and lunch, it is air-conditioned so no need to worry about getting cold. It is situated in a nice, quiet neighborhood not very far from Termini (you take tram 5 or 14 to get there). Donatella's daughter Morgana greeted us with a huge Christmas cake and a chocolate, which we enjoyed!!! She was also kind enough to book us a taxi on the day of our departure. Would definitely recommend it to anyone traveling to Rome!!!
P.S. if you are a big person you will probably won't fit in the shower, so check out Donatella's two other apartments, i'm sure you won't have any issues :)
