Although Carlo was out of town while we stayed, he gave us all of the necessary arrival information far in advance. Sergio (a friend or maybe a relative?) lives in one of the apartments above the studio and came right out to show us how to get to the private parking area, where the best places to eat were, and showed us around the studio. Sergio was very friendly and helpful.
The studio itself was perfect for a quiet stay in Bologna. It's just inside the historical center of the city, but not in the midst of things. We could easily walk ten minutes into the center for the Piazza Maggiore or the Quadrilatero district (for foodies). The pastry shop across the street is wonderful - get the cream-filled "bomba"!
The Wi-Fi worked great, the bed was comfortable and easily sleeps two adults (and my husband is a large man). The private parking was SO helpful to have, as we used Bologna as a headquarters and took day trips to Pisa (about 2 hour away) and Maranello (1 hour). There are some very cool archaeological relics left on display where they were found during renovation (under the floor), and there is an actual well with water and services a humidifier in the studio.
The only downside to this studio: 10 minutes MAYBE of hot water for each shower. You either have time to wash your hair or shave - you can't do both. But you can wait another 10 minutes between showers and hop right back in for another hot session.
