Amazing location if you're planning on checking out Ancient Rome - is is right next to the Roman Forum and Collosseum, right behind the Vittorio - amazing. Also close to the river if you're planning on spending a few evenings in Trastavere for food/drinks.
In addition; the hosts are really lovely. Very generously gave us a late check out on our last day as they didn't need the place back.
Also very quick to respond.
