We stayed for two nights with two couples and two others (six total). There was plenty of room and we were very comfortable. Having two bathrooms was a huge plus for our group. The apartment is well done and convenient to grocery stores and walkable to the surrounding areas and metro. The host, Lorenzo, was very responsive and helpful with all our questions. He even saw us off and made sure we had a taxi to the centrale station. I would highly recommend this stay, it was one of the best we've ever had via airbnb.
