Off the beaten tourist track but just steps from the Materdei metro station, this unpretentious yet charming café is a favorite with locals who come to enjoy a moment of peace and quiet, complete with a good espresso and a homemade pastry. The warm welcome makes it easy to become a regular if you're staying in the neighborhood for a few days. The delicious lemon juices, sweetened or unsweetened, are freshly squeezed to order using fruit picked from the family garden.
