Hi Czarni,
Giorni is a good shop for soldiers, and easy to reach by underground train, stop Ottaviano. A this time they offer many figures of better firms with discounts of 20 or 30%.
Another shop well equipped is Alfa Model Viale Somalia 216 www.alfamodel.it
stop Barberini or Termini with underground, then the bus 80 from Barberini, or 38 from Termini.
Good shopping
