The apartment has 2 independent double bed rooms and so is big enough for 4 people even though it felt a bit crampy compared to some apartments we stayed in at Venice/Florence. But the location is fantastic. It is a 2 min walk from which has enough and more restaurants. The place is lively with souvenir shops and the a farmers matket in the morning. All the sights of rome are within 2-3 kms from the apartment and can be walked or take a 10 euro cab ride. As a host, barbara made sure to give us almost all the information about rome with a well marked map. I would guess we were unlucky that 2 ACs were not working for the period of our stay but thankfully ot was not too hot. Even though it is not in plane site, the basement bedroom does not have a door and so privacy can be a concern. All in all a great place for 4 and an awesome location.
