I can't say enough how much I loved this flat. It was immaculately clean, beautifully decorated, and wonderfully located in Trastevere. As another reviewer mentioned, the second bedroom does not have a door, but it's still rather private. The flat was very easy to find and Paolo welcomed us in person. He had great restaurant recommendations, but there really isnt a shortage of great restaurants and bars within a 3 minute walk. Tons and tons of bars and a University campus are nearby, so this area can get loud on the weekends. If you close the window shutters the noise is reduced greatly. If you are sensitive to noise, you might want to look elsewhere. I was not bothered one bit by the noise, since most of it was in passing and only until about 2am. Be sure to check out the rooftop garden. It's well furnished and offers great sunrise views. I really can't stress how clean this place is. Easily one of the cleanest Air Bnbs I've ever stayed in.
Note: The stone roads are a bit hard to navigate if you have luggage, so I would recommend using uber over walking to the taxi stand.
