Barbara's room is an excellent choice. It's only a room with a shared kitchen and bathroom, but you pay for this one, and the cost is according to this.
Barbara is a very kind and helpful person. SHe waited for my late arrival (due to my flight that was late). She helped me all around.
The room is convenient, quiet and has also a desk to work. There is also fast wi-fi .
One and only negative I could say is that in the bathroom there is a bad smell , probably because of the hydraulics. I think Barbara will take care of it.
In general, it's a good low-cost choice for Bologna, I strongly reccomend.
