We had a great stay at Giovanna's place. The locations is superb, extremely close to the Forum Romanum and the Altare della Patria. The apartment is very neat and includes a kitchen, which we used every night to cook dinner.
Giovanna is very kind and hospitable, and eager to share her knowledge of Rome. The communication also went good. All with all, I can do nothing other than strongly recommend a stay at Giovanna's when visiting Rome.
