We stayed in September 2018 for a week at Federico’s place. The apartment is simple, modern, clean and appropriate for two people.
What we liked about the apartment:
That the apartment is in walking distance to most major tourist sites like the Vatican, the Roman Forum, Piazza Navona, Pantheon etc.
There are many restaurants and bars in the neighborhood. Trastevere is a nice place.
The apartment is equipped with an air conditioner.
The windows are new and noise absorbing.
The bed mattress was comfortable.
The apartment has a modern bathroom and a nice little kitchen with a spacious fridge.
The shortcomings of the apartment are:
There are many bars right next to the apartment. On the weekends, the street can be quite noisy. This is only a problem if you do not plan to participate in the party.
The apartment has very limited storage facilities and there are no bedside tables.
You can watch only Italian stations on the TV (no BBC, no CNN).
The apartment has only two chairs one of which was quite unstable.
We had only one key to the apartment and the door to the floor could not be locked.
Overall, the apartment is quite convenient for a short stay in Rom, but considering the size, furnishing and facilities, I think the apartment is a bit too pricy.
