Our stay at "The Rear Window" on Campo de Fiori was a complete success for my wife and I. Communication leading up to our arrival as well as perfectly timed texts during our stay to see how we were getting along made the entire process seamless.
The apartment is well laid out and very comfortable with all of the amenities you would expect to find in a self-stay. The description of the apartment is very accurate and we found no surprises during our 5 days in Rome. We were a little concerned about possible noise from the piazza at night however just as previous visitors descriptions suggested the apartment is situated such that it provides a very quiet, peaceful sanctuary.
The location is great as you are within minutes of most sites (we easily walked to the Borghese Gallery/Spanish Steps, to the Vatican as well as the Colosseum/Forum). A plus was being able to grab a "beverage" just outside our door on the piazza in the late afternoon before heading out for dinner.
As we were leaving via Termini Train Station (rental care pick up there), we easily caught the express bus just down the street from the apartment (4 minute walk).
We highly recommend "The Rear Window" apartment and will certainly look to stay again when back in Rome.
