I enjoyed my stay at Sabrina's place. She was very sweet and provided strong communication.
The loft is in a good location that is within walking distance to Vatican City (15-20 minutes). I decided to walk or take a taxi to most places. In Rome, taxis are cheaper than Ubers. I would say the taxi stand I found was about a 5 minute or so walk from Sabrina's place (you can't wave down a cab in Rome).
I enjoyed my stay, but keep in mind, if you are 6 foot 3 or taller, there may be parts of the apartment (specifcally the bathroom) where your head will likely touch the ceiling. I'm 6 foot 1 and the ceiling was fine and didn't bother me.
The next time I come to Rome, I would definitely consider Sabrina's place.
