If you're at Bologna airport, a bus that takes half an hour and costs 10 euros will drop you off in front of the train station. It's a good place to look for a hotel in the center that will suit you so you're able to visit different city monuments and artistic things from the Emilia Romagna, like Ravenna, Modena, Ferrara, etc. Even Florence or Venice which are about an hour and a half away. All those places are filled with art and culture, and on top of that, good food. I'll tell you about a little place in the Hotel Excelsior, but on the same sstreet from NH to Mercure. Also the city center is a few minutes' walk through the beautiful arched streets lined with shops.
