This was a great place to stay in Bologna!
The apartment is just off the main piazza in Bologna. Some of the best places to eat are literally footsteps from the front door to the building. Since you are so close to some restaurants, noise is to be expected. The apartment directly overlooks a courtyard; however, they shut down at midnight and after that things get quieter. I'd recommend ear plugs if you are a light or early sleeper.
The apartment is plenty comfy and has everything you need. It really feels like a home away from home. I would stay there again.
