Starting with the room: according to the photos, spacious and well lit by daylight. The bathroom is tiny but functional.
The kitchen: I found small and difficult for two people, or more, to cook or stay in place. And if there has a "large" number of guests, it can be a problem to reconcile the time to make your food.
The sights (Coliseum, St. Peter's Basilica, etc.) are accessible by foot, but be prepared for a walk.
Overall the stay was good. Good for anyone who wants to have a real experience of living in Rome.
