We had a great stay at Carlo's cute and tastefully restored cellar apartment with the inside well and exposed glasscovered historic remnants in the floor. One of a kind, very cody and private it is situated perfectly for walking all around the center of Bologna (and for temporarily parking a car just outside the traffic restricted area for picking up your stuff, should you happen to be going by car). The communication before our stay and the welcoming by Carlo's dad was a pleasure. As stated the well does give the place a slight hint of humidity which might offend the most sensive of noses. We loved it and would not hesitate to go back.
