We booked a reservation in this Studio in Bologna because it looks so charming in the pictures and its location seemed ideal for us. Most of the reviews were positive though one did mention a problem with a moldy or mildew odor. We should have paid attention to this review because the smell was strong and inescapable due to the studio's physical situation - 100% underground with no windows. This might not be a problem for many but for us it proved uncomfortable and we left early because I had trouble sleeping comfortably. A charming place with the above caveat and about a 20 minute walk to the center of town. Another positive...it was about a 6 minute walk to absolutely the best gelato of our month-long stay in Italy. The studio is also quite close to a charming park area with a lake, fountains, tree-lined paths, etc.
