Stefania has a big appartment with lots of beautiful paintings, 2 bathrooms and the house is situated not far from the city-center, but the district is clean, green and relatively new.
I can definitely advice you to stay at Stefania's appartment, if only you dont mind cats. Stefania has two brautiful cats.
P.S. I dont advice you to live in the city-center of Bologna, the houses thrte are very old, its overcrowded, always traffic jams, very few fresh air and no trees.
