We had a great time at Sabrina's flat, everything was just like the pics and reviews, except none of them mentioned the comfy bed! We had fast responses from Sabrina whenever we messaged her with questions. If you are taking public transportation as we were the flat is a bit of a commute to the main sights, and be aware of the metro strikes, as we were stranded near the center of Rome one night! If you rent a car it will probably be more convenient for you.
Sabrina gave us a tour of the flat, gave us some basic instructions and handed us the keys. She worked most of the time we were in Rome, but she always responded to our messages as soon as she could! She was very nice and we recommend her flat to anyone wanting their own place and space during their visit to Rome.
