Federico's apartment is spacious, has great structure and natural light. The apartment is good if you looking for something less expensive than Trastevere or the center of the city. I would say that it would accommodate 4 people well. The location is super convenient. There's a tram line very close to the apartment (5 min walking) that leaves you to Trastevere and Piazza Spagna, which is great. My husband and I spent a week there, working most of the time. We had a little inconvenience, but it's not related in anything with Federico's apartment structure: there's a hospital near the building, so we heard to many sirens all the time! Something that wouldn't bother someone that is only doing tourism. The host was super responsive all the time. We hired the shuttle service that he offered and it worked well.
