We stayed in Ari's apartment during the Easter weekend. She is a very nice and helpful host who took time to introduce us to her beautiful apartment. It had both a balcony and a terrace with beautiful views over Rome. The bedroom was nice and bright.
It is good to notice that the flat is located on the 6th floor in a 18th century building. That means there is no lift. If you don't have any problems walking up and down stairs you shouldn't hesitate booking this flat.
The neighborhood Monti is a vibrant part of Rome with many nice restaurants and bars. That given we were never disturbed by any party animals outside. Instead it is a good location to discover Foro Romano, Colosseo, Piazza Venezia and many more of the "musts" in Rome. Monti in itself is also worth discovering.
