We had a great stay at Gabriele's Rome apartment! Has a charming view of the St. Croce Basilica from most windows, and the location is relatively very centric. Also very comfortable for our group of 4, everyone had a comfy bed. My group and I also loved that it really lets you experience Rome as a local (or at least gives you a feeling of how it would be like to live there) You can easily walk to two major tram stops (SanGiovanni or Porta Maggiore), or even better I suggest you figure out the route of TRAM #3 which will drop you off right in front of the apartment, and it also can take you all the way to the Colliseum.
On a side note, Gabriele was super welcoming. He offered us rides to and from the train station upon our arrival. This was a huge plus for us, as we had my grandmother traveling with us. Great experience overall.
