Gianfranco is a perfect host and offers a great accommodation in Bologna. His communication is always very fast and friendly. The place is a very nice and big apartment, is absolutely clean and comfortable - it just feels like home. There even was Italian breakfast and coffee available for free in the kitchen, which we admired.
The location in the city is also fine, calm surrounding, a few bars, restaurants and stores are within minutes. The walk to the city center, Piazza Maggiore, is only about 10 Minutes.
Overall we can only strongly recommend Gianfrancos apartment, if you are looking for a place to stay in Bologna. It was one of the very best AirBnBs we ever were allowed to use. There is nothing to improve.
