Marco is an amazing host. Communication was fluid and he was always willing to help me with anything. The apartment is really well located in the heart of Bologna and indeed very comfortable. 15 minutes walking from the train station and the main bus lines are right at your doorstep. Only a few minutes from Piazza Maggiore. It's just like the pictures, very clean and with everything you could need for your stay. Have nothing else to say but if you ever visit Bologna, Marco's place is an amazing place.
