Mimma's apartment was very spacious and had plenty of room for our group. There are about 10-15 stairs to enter the apartment however they are very manageable. We stayed during a particularly hot heat wave in Rome and the A/C in the apartment was very cold and worked perfectly for us. The neighborhood is close to a lot of shops and restaurants but the street noise is pretty quiet. It is about a 10 minute walk from the metro stop. We only stayed one night but we enjoyed our time here.
