The place has everything you need for a nice and pleasant stay if you don't mind the lack of a view as it is located on the ground floor. Everything stated as amenities in the listing is presented - iron, washing machine, cooker, wifi, etc.
The neighborhood is nice and quite. Trastevere is 30 min away by walk, which for me and my girlfriend wasn't a problem as we walk to work everyday for the same amount of time. However, if you are not much to walking, you can catch tram N8 to go there or to the historic station (piazza Venezia) from where you can go in any direction you'd like. The tram's station is on 3 mins from Federica's place, which is very convenient. However, keep in mind that you will need about 30 mins to get to the city's historic center with the tram.
