We had one night in Bologna and wanted to stay at a place that wouldn't break the budget, but would be convenient, especially since we had our 9 month old with us.
The Alloro Suite Hotel fit the bill perfectly. It was amazingly cheap, just $70 or so/night for two fine rooms (one for us, one for our au pair). The rooms were spacious and clean, with very large and well-appointed bathrooms. The neighborhood was just that - a neighborhood - with no tourists, but the historic section of Bologna was a 10 minute drive, at most.
The front desk staff were casual, to put it mildly. They spent a good deal of the time on the phone, whether helping other clients or talking with friends, we couldn't stay. But we were able to interrupt them for some truly helpful service: an off-hours espresso from the kitchen, directions to the historic district, and a recommendation to a local restaurant.
The breakfast was really terrific for the price. Good variety, a lot of healthy options, something for everyone.
Finally, while you're in the area, don't miss Ro'Coco Restaurant, about 1.5 blocks away. The clients are almost entirely locals, the food is amazing, and the prices are low. The hotel staff will point you in the right direction. The house white is cheaper than water and really good; the pizzas are crisp, the pasta perfect.
