Filippo's place is perfect. Great location, plenty of restaurants and cafes on the block, in the heart of Trastevere, short walk to Piazza Navona, Campo di Fiori, Campidolgio etc. Yet, the apartment is incredibly quite and serene.
The space is beautiful, the living room is perfect to sit down and read or work (great desk for working), large windows makes the space have lots of natural light, great kitchen (with all the appliances), spacious and clean bathroom, comfortable bed etc.
Would definitely recommend and wishing to visit again.
