My staying at Sabrina's place was just perfect. I felt all the time like at home. The atmosphere in the house was quiet, familiar, comfortable all the time, and all the other guests were very nice as well. The position is unique, because you are very close to Trastevere, a very nice neighbourhood of Rome, but especially because you're close to the train station and to the tram stops 3 and 5 (and trams and trains are the public transport means which are more frequent and work the best; I would suggest not to rely on busses...). So I was very close to everything I wanted to see in Rome, but at the same time I could count on a very quiet place in the night.
The check-in was very smooth, and Sabrina was very careful and clear in the indications of how to reach the place.
The room was very cosy and nice, very clean, comfortable (and it's just super to have your own bathroom attached to the room).
I would highly recommend this place if you plan a trip to Rome.
