Patrizio was a wonderful host. The apartment was spotless and comfortable inside, and his recommendations for places to visit and eat around town were spot on. Location-wise, it's a short walk from the most popular parts of Bologna and easily walkable from the train station.
Another reviewer mentioned that the area was rough, and I'd have to agree. One evening as we left the apartment building there was a man on the apartment steps shooting up – this was unexpected, but not totally surprising given some of the other shady characters seen hanging around. This is absolutely not the host's fault, and the inside of the apartment building is extremely secure and quiet. But keep it in mind if you're travelling alone, with kids, or otherwise put off by that sort of thing.
