As Bologna is a city crowded with tourists and visitors to the many trade fairs, it is vital to book your accommodation as soon as possible, otherwise you might only find very expensive options (or none at all).
Any accommodation in the city centre is viable, as the congress venue is reachable by bus, yet if you want to search for closer hotels, use the following address as a reference: Via Gobetti 101 - and look for solutions in the nearbies.
