We had a very nice stay. The apartment was as we expected. It is perfectly located, at the edge of Trastevere, everything in this lovely neighborhood close by, but without too much noise and nuisance at night.
We obviously enjoyed the view and natural light in the flat, as well as the terrasse.
One major downside however, if you are looking to sleep in during your stay: some big windows are cruelly lacking curtains or shutter.
Do expect to wake up with the morning sun.
