I cannot recommend this apartment highly or strongly enough. The room itself was perfectly comfortable, although I did need to buy an oscillating fan to keep myself cool; the desk was essential and very useful; the kitchen was entirely adequate and fully functional for anyone wishing to make a hearty meal or a quick snack. The apartment is ideally situated because it is close to the Cipro station of the Metro A line of the subway. I can't stress how awesome and useful this fact is because the Metro A line goes straight to the Vatican and also to multiple downtown locations. Further, the zone in which this apartment is located is entirely Italian so if you want a more authentic experience stay here. Most importantly, Virginia, Diana, and Lorenzo (and Fritz the cat) are about as good-hearted, nice, friendly, generous, and humourous as one can find in Rome. They were consistently patient with my Italian, and indeed they substantially aided me to improve my language skills in their language. They never once showed anything less than a gentle but firm resolve to help me, for which I am earnestly grateful.
IN SHORT: Book this flat, it's great, and is only overshadowed in by the people themselves who are superb examples of warmth and kindness.
