Very nice and cosy B&B, could be perfect place to stay in Bologna for a long-weekend trip for a couple, which was ours. Only 3 rooms, but two bathrooms, everything superclean (even when we were for 2 nights, we had a compelte change of linen and towels, and cleaning done in our room). On our arrival in the morning (not within the written fixed hours) we telephoned to the owner an hour before, and we had no problems with check-in. The owner speaks both Italian and English. Rooms are isolated from each other, the street is quiet. The noise from the boiler can be easily turned off :) Breakfast was the usual italian, brioche, some crackers, jam, butter, juice.. The great plus is a small coffee machine in the hall, so you can use it by yourself everytime you want to make coffee. In general it was a very nice surprise to find this place for not such a big price, i can only recommend to all who travel to this town.
The only negative moment might be the location -about 20-25 min. walk to city center, about 15 min. from central train station. But if you don't mind walking a bit, it is not actually a big problem, also this part of the town is very quiet, and the street to the center is full of small coffee bars and shops.
