The loft is simply drop-dead gorgeous, so much so in fact that I'd advise travelers to be careful because they might not want to go outside and explore the city. It is extremely stylish and comfortable, with a massive window to let the light in, a bed to die for, and a gorgeous hardwood floor.
It is also located in just about the most comfortable area of the city. A 5 minute walk gets you to Piazza Maggiore, and you will pass by countless great bars and restaurants along the way; whereas a 10-15 minute walk gets you pretty much anywhere within the historical centre. It is a vibrant and lively neighborhood, without being overrun with tourists, but rather with locals and students going about their haunts.
As for Donata, she was not only very kind, welcoming, and helpful with tons of tips about local spots, but she had also taken great care to fill the apartment with all kinds of comforts. There was water and wine in the fridge, coffee and all sorts of teas, honey and jam and crackers, candies, spices and cooking products; anything you can think of and more, and certainly far more than most Hosts would bother with.
Overall, I had a splendid stay and would love to come back again. I recommend Donata and her loft very highly to anyone wishing to enjoy Bologna.
