The apartment was very clean and confortable. It's close to the train station so it's perfect if you have to take a train in the morning, and it's in a very quiet neighborhood.
Daniele was very nice and flexible with the check-in hour, and even he wasn't in the city when we arrived, he sent a friend to open us and to give us the keys, at 9 in the morning.
If you plan to visit Bologna I strongly recommend you to stay at Daniele's place!
