Monica and her sister have been very communicative, reactive and kind.
The appartment is placed in a strategical position for visiting on foot all the city center, very close to Piazza Navona, Chiostro del Bramante and beautiful streets (Via del Governo Vecchio, Via dei Coronari). It's surrounded by good restaurants.
The appartment itself is decent and the terrace would be great in all seasons except winter), the furniture is old but functional.
What we didn't like is the bathroom (really small and uncomfortable), the sheets and blankets that are very old, and the acoustic insulation that totally sucks (you can easily hear people walking on the streets four floors below, imagine when they laugh crazily on Saturday evening...)
The appartment cleaning is also quite disappointing.
Anyway, for the price that you pay, what you get is ok.
