This eccentric home is a little gem on the edge of Regola and overlooking the Campo de' Fiori market. It occupies the top floor of a historic fifteenth-century building that once belonged to Vannozza dei Cattanei, courtesan and lover of Cardinal Rodrigo Borgia, whose family crest still adorns the outside. There's no getting away from the fact that the living room is small, but there is just about space for an extra person on the bed. Really, though, this flat is all about the bedroom. The wallpaper is the first thing you notice, but pretty much every detail has been carefully thought through, and they all come together wonderfully. The host, Paola, lives on the same floor of the building, so she's always close by should you need anything during your stay.
