What an awesome location; walking distance from so many things like vatican, old market (Campo dei Fiori) with good bakery (Forno), piazza navona etc. Please try the pizza bianca and rossa:)
Supermarket across the street, nice cafés and restaurants close by. We just spend a super week with our two sons (10 and 13) in Rome! They loved the large tree "bunk" bed and decorations in the bedroom. Apartment in very old building, felt like authentic Roman, with even a running elevator to use if you're too tired and already walked long distances;). We would definitely love to come back and stay here again.
