We stayed in room 8 at the Delizia Estense in July 2010, room 8 is a bit of a converted attic room I guess. Though it can't have been much more than 40 square feet (if that!) The room comfortably slept myself & my partner in the bedroom, as well as my sister on the sofa bed next door. The apartment uses space extremely well and never feels cramped, with sliding doors on the bathroom/ensuite and cupboards built in wherever possible offering lots of storage.
In addition to this there are cooking facilities, including a fridge freezer, microwave oven and double hob as well as cutlery, saucepans etc. Breakfast was provided from 8 to 10 and consisted of pastries, cake and hot drinks/juice. All very tasty!
Despite the weekend being 38 degrees, (30+ at night) the room remained cool thanks to the aircon. We had a lovely time in Ferrara, which is a beautiful city of cobble streets lined with bars, restaurants and some stunning architecture. All within a 10 min walk of Delizia Estense. The service at the hotel itself was friendly and informative, and whilst we didn't make use of the free bike service, it's a great idea as Ferrara's quiet roads lend themselves to exploration.
I'd highly recommend the hotel, and expect to return in the future!
