Alessandra's place is very comfortable, it had everthing I needed. I only stayed for two nights, but it's a place where you can easily stay longer. There is a option to cook your own food, make your own coffee, ect.
The busses in Bologna work very good and the place is easy to reach. Walking is also possible, it will take you +- 35 minutes to the city center.
Alessandra is very helpfull and nice to talk to. See makes you feel and home and is always willing to answer questions.
