I travelled to Rome for a wedding and stayed at Marco's place for 3 nights. Communication with Marco was super efficient, no issues whatsoever. He organised a car for me from the airport and back, so I had nothing to worry about, but enjoy wondering the streets and piazzas of Rome. The flat is all about location, location, location. Right off Campo de Fiori, all of historical Rome is within a short walk. Quiet at night, the church bells ring in the morning for a friendly 'good morning'. My only issue was with the light (or lack of) in the room. Being used to awake by natural light streaming through a window, I struggled with that. On the flip side, the bed is very comfortable, and I am picky about mattresses and pillows.
If one needs to work, that'll be an issue, but then again, who wants to work while on a visit in Rome (-: overall, a very convenient place to base oneself when in Rome.
