Carla’s is a lovely host. The room is a little small for 4 people but a decent sized room for fewer people. It was very clean and decorated nicely. The room is an hr walk or 30 min bus from the centre but the area seems safe and the supermarket was extremely convenient. The air con worked nicely and was ESSENTIAL after a long day. P.S. maybe don’t go to Bologna in a heatwave like we did 🥵
