Maria's place is really close to the center of Bologna; it takes no more than 10 minutes. There are several lovely "trattoria/osteria" around the place, very convenient to try typical Bologna food!
Though we didn't stay very long with them, she was still very friendly, kind and helpful. A very good hostess indeed! The room is really big and spacious with lovely decorations. Strongly recommended for people who'd like to visit Bologna!
