Granny's place is on the 4th floor with two balcony's - one east and one west - so you are able to enjoy sunshine or shade at your favorite times of day. Additionally, I found the elevator very helpful for my 70 year old mother with a cane, as well as my family's large luggage items. We still needed to climb 10 or so steps from the street level, but it beat having to climb up four floors. Not every place has an elevator, so this was a helpful surprise.
The space provided in this apartment was plenty for my family of five, visiting for 4 days in Rome from Michigan. We enjoyed a spacious family room, and spacious bedrooms, and fully equipped kitchen.
Finally, we were thrilled to be less than one block from the Metro station (Subway), and street car station. With a coffee shop right by the stations, and daily fares (costing roughly 7 Euro's), this made getting around simple. Just pick up your ticket fare from any tobacco shop.
