My sister and I stayed at Pina's at the end of October. Her flat exceeded our expectations. It is modern and comfortable with all basic needs covered. The beds are very comfy (the sofa bed is available should you need an extra bed). Communication with Pina was fluid throughout. Herself and husband Leonardo picked us up from the airport for a reasonable fee. We were greeted at the flat with a bottle of lovely local white wine. The neighbourhood is well served by the metro, connecting it with all major attractions. The local feel of the area enhanced our experience. Away from the touristy areas, Quadraro is ideal to see how local Romans go about their day to day lives. It is quiet and leafy. It also offers good quality food in its various cafes and restaurants at very affordable prices. There's even a 24-hour supermarket nearby with a great selection if you prefer to dine at home.
We cannot recommend Pina's place highly enough and would gladly stay agin next time we are in Rome.
