Place in specious and clean. We travel as family 2+2, but it would easily fit 8 people. There is two bathrooms and nice balcony in the apartment which is a big advantage. It literally 5 min walk from Vatican, you can see top of basilica for the bedroom window. As well you can walk to Colosseum , it took us about 30 min. Close proximity to car park (you can book it in advance) and bus stop.
Communication with Matteo was great, he saw quick to respond to and queries and resolve any issues.
There is hospital very close from the apartment, so there a lot of ambulances driving on the signal during night
