My wife and I stayed at Fabia's place for 4 nights. By the time we left we felt like we were local residents. Imagine walking out of the front door of your apartment and stepping into a vibrant, colorful farmer's market (every day except Sunday)! We loved it.
Fabia's apartment is spotlessly clean and spacious. The bed is very comfortable. The bathroom is big and has an American-size shower. The WI-FI is great. The location of the apartment is outside the tourist area so you are walking among local residents in the real Rome of today.
There are buses across the street to take you close to the main places of interest in Rome. There is a metro stop very near the apartment, Cornelia, which was temporarily closed for maintenance. Single tickets for the buses and the metro can be purchased at any Tabaccaio shop but 1-day, 2-day and 3-day passses only from machines at the metro stations. I recommend highly the Joseph Ristorante located about a 10 minute walk from the apartment, with the suggestion that your order only one "primo piatto" of pasta and one "secondo piatto", the steaks are very good, and ask that each be divided in two plates, if you are two persons. The pasta portions especially are gigantic! Finally I recommend the Gelateria "I Tropici" neaarby. and its ts hazelnut and fondente.
