The apartment overlooking the Duomo was a great location - easy to get to all tourist sites, clean, and a good size for a couple. The terrace was the real draw to this apartment, and even though the weather was on the chillier side, my husband and I still sat outside at the end of our days there to have a glass of wine. Federico and his business associate, Matteo, were there to welcome us when we arrived and gave us a lot of information on the area and suggestions for where to eat throughout the city. Communication with them was quite easy. The only cons to the apartment are as follows: Firstly, as written in the description, this is a walk up and a steep walk up at that. This was fine for us, but definitely should be taken that into consideration when booking; and secondly, though the view of the Duomo and Campanile is stunning, the area was quite loud at night, especially on Saturday and Sunday. Overall, despite these cons, I would recommend staying at Federico's place.
