We stayed at Michele's place for two days. We were seven people, and the place was perfect for accommodating everyone. It's a big apartment with walkable access to Bus (250m) and Metro (700m). Michele is a fantastic host; he helped us flexibly to accommodate the check-in. Also, he suggested to us the best places and tours see around Rome. (The view of Roma from the balcony is impressive, though :))
I will recommend his place if you are travelling in a group. It's comfortable and homely!
