The location is great, 15 minute or less walking distance to the Colosseum, Palatine Hill, Roman Forum, etc. To get to the Vatican and St. Peter's Basilica you will need to take the metro A train, but it's pretty easy to get to.
The property is located in a safe area, with spacious bedroom and living room. There is only one window (in the bedroom), the rest of the house is pretty dim. The kitchen and the bathroom are right next to each other, and they are cramp.
The host Cate has been great. Very responsive to every one of our inquires. This is a convenient place to stay while visiting Rome.
