I had a wonderful time in Marzia's apartment. It's fully equipped, you'll find everything you need if you want to cook by yourself, coffee facilities etc. Check-in was excellent and I was also allowed to arrive an hour early. Bologna is a wonderful place, and from Marzia's apartment you'll reach the city center in around 25 minutes by foot. There are various bus connections available as well, but walking under the famous arcades is agreeable even in summer heat.
