It was perfect. Rossana and her friend Christina (for the english conversation) were very kind with us. They gave us practical and very useful informations about the town, and a real italian restaurant.
The room was very big with a private bathroom not in the room but it was not a matter really. The room was nice, the bed was perfect and the cleaning done each day!
Really, you don't have to search for another place in Rome. The apartment was central and quiet.
I say again, Rossana, thank you so much.
