I sincerely recommend Victoria Apartment while visiting Rome. It was exactly how is described on AIRBNB: very clean, intimate, with big enough, good taste and sunny 2 sleeping rooms. Kitchen and bathroom are equipped with everything you need for a few days trip. The neighborhood is very nice, safe and quiet. Supermarkets and a coffee shop are in front of the building. Also many places to eat for all budgets and tastes, starting with fast food KFC or McDonald's type or a very good restaurant called Joseph, which I also recommend as a must do it while you are on this journey. The subway station Cornelia is at only 1-2 minutes from the apartment, which is an advantage and a very important asset when you want to see so many attractions in a very short time in Rome.
I may not conclude my review without mention the host - Andrea. He was very helpful and anxious to give us many tips&tricks about tourist attractions, public transportation or local needs. He also helped us with the transfer to airport in the middle of night, so it's good to know that you have in Andrea somebody to rely on!

PS - Is good to know when you make the plans to visit Rome, that you should add at your budget an extra tax that you have to pay when arrive to apartment: the City Tax, which is 3.5 euro / day / person. And which is extra than cleaning fee and administration fee for the place you stay.
