We stayed in the Dante Suite for 5 nights and were very happy with our stay. The place is large and spacious and was nice and clean on our arrival. It is located within walking distance of all the city's major sights and the area feels safe at all hours. The carpark was fantastic and spacious enough for a large car (although manoeuvring can be a bit tight - we had a Skoda Octavia and managed to get in and out easy enough).
Overall a great stay and we would certainly recommend this to anyone looking to stay in Bologna.
