We had a lovely stay in Domenico's apartment. It's very spacious for two people, well-equipped and very clean. The bed is big and comfortable and the flat stayed cool on hot days. Check in was very easy and Domenico was super helpful, especially with recommendations for places to eat (would recommend Osteria dell'Orsa and Parlor for evening meals). The flat is in a good location 10-15 minutes walk from Piazza Maggiore in the university district. The street is quiet despite the area being bustling. Would thoroughly recommend staying here on your trip to Bologna :)
