We had an enjoyable stay in Lucia's appartement. The location is really good, close to town and lots of public transport to get about with.
Communication and check in was very fast and easy and the private parking spot is a bonus if you come by car.
Plenty of room to sleep 6 but only if you dont really plan on doing a lot of cooking as one of the beds is in the living room/kitchen.
For a group of 6 wanting to visit Bologna I highly recommend.
