Great room—Huge (with a desk and another table for eating) as well as free space. The apartment is on the eighth floor with a nice view of the neighborhood from the room's window. Kitchen is well equipped and the bathroom worked well. Claudio is a super chill , respectful and generous host, always available to make you feel at home.
My only caveat is that the building is somewhat far from the city center and I didn't know is that public transportation in Rome is horrible. So keep in mind that communication with the rest of the city is somewhat clumsy. If you plan to leave early in the morning and spend the whole day sightseeing, you'll be fine. But if you plan to have a well-connected flat where you can come back during the day, don't count on it. It can take more than one hour to get back from some touristy zones like Trastevere. Other than that the place is great and awesome price/quality ratio.
