It is, as advertised, a great appartement located in the useful center of Rome: most places are reachable by foot. There is a lot of animation almost below, at the fountain, with its advantages (life, highly quoted places by trip-advisor, even just 5 and 15 meters away of the front door !), but also a bit of noise by night (but reasonable).
It was a pleasure to jump into the bath-Jacuzzi after walking full days in the city.
Altogether, after renting 7 nights here, I am very happy and would come back if I come to Rome another time.
