Me and my wife spent a week in Rome in the end of February and the beginning of March. Cate's apartment was a perfect base for our walks and adventures in this eternal city. It is situated a stone's throw from Piazza Navona and a very short walk from Campo dei Fiori, so there's a lot of restaurants and bars nearby. But the apartment is very quiet, it is situated in the top floor (no elevator & many steps but we liked it that way). You can sometimes hear church bells and squawking of seagulls, and they are nice sounds in Rome.
It is easy to walk to most places, to Vatican or Trastevere, for example - and if you like to go further, many bus routes are routed via nearby street. There are two supermarkets just round the corner. The wi-fi worked well in the apartment, and there's a nice view over roofs from windows. Our only problem was a heating, there was some block in the gastherm and heaters stopped working - but Cate solved the problem within few hours. So all did end well!
